What change in pressure occurs in a party balloon that is squeezed to one-third its volume with no change in temperature? The pressure will increase to three times its original pressure.

What change in pressure occurs in a party balloon that is squeeze to 1/3 its volume with no change in temperature?

A balloon when squeezed to one third of its volume and with no change in temperature the pressure increases up to three times its original pressure. According to Boyle’s law volume is inversely proportional to pressure.

When boarding an airplane you bring a bag of chips while in flight the bag puffs up because?

The bag of chips is sealed airtight at sea level will have 1 atmospheric pressure. When the flight takes up and as the altitude increases the pressure in the flight cabin reduces. The pressure inside the package is more when compared to the pressure in the bag.

When a chocolate bar is cut in half its density of each half is?

When the chocolate bar is cut in half the density of the bar is therefore unchanged. In other words when the chocolate bar is cut in half both the mass as well the volume becomes half in each piece. As a result the calculated density which is the ratio of mass to the volume remains unchanged.

What causes atmospheric pressure quizlet?

Atmospheric pressure is caused by the weight of air just as water pressure is caused by the weight of water.

What occurs when a gas is compressed quizlet?

What happens to the particles in a gas when the gas is compressed? The space between particles is reduced. Explain why heating a contained gas that is held at a constant volume increases its pressure. The increased kinetic energy of the particles causes collisions to occur more frequently and with more force.

How much does the density of air increases when it is compressed to half its volume?

Atmospheric pressure equals the pressure under 10.3 m of water and so can push water no higher. By how much does the density of air increase when it is compressed to half its volume? It doubles.

What happens to the internal pressure in a fluid flowing in a?

What happens to the internal pressure in a fluid flowing in a horizontal pipe when its speed increases? The pressure decreases when the speed increases. … The speed increases as the air flows over the wing so the pressure decreases.

What change in pressure occurs in a party balloon that is squeezed to one third its volume with no change in temperature quizlet?

What change in pressure occurs in a party balloon that is squeezed to one-third its volume with no change in temperature? Pressure increases by a factor of three.

How does the density of air in a deep mine compare with the density of air at earths surface?

Density of air at the surface is less than the density of air in a deep min. The weight and pressure at the bottom of the mine is increases by adding the air filling up the mine. The greater pressure in a gas means greater density based on Boyle’s law.

What happens to the air pressure inside a balloon when the balloon is squeezed to half of its volume assuming the temperature remains constant )?

What happens to the air pressure inside a balloon when it is squeezed to half its volume at constant temperature? … The atmospheric pressure decreases as they rise so they expand.

What happens to a chip bag as you drive up a mountain?

The amount of air in a bag of chips is fixed. If the package was sealed at a lower elevation and carried to a higher elevation the air inside of the bag will swell against the reduced atmospheric pressure. … At high elevations it boils at lower temperatures because the atmospheric pressure is lower.

What happens to the air pressure inside a balloon when the balloon is squeezed?

By squeezing the balloon you reduce the space the gas particles can occupy. As the particles are pushed a bit closer together they collide with more so the pressure from the moving gas particles increases. If the volume increases its pressure decreases.

When a chocolate bar is cut in half its density is: unchanged. A metal block has a mass of 5 grams and a volume of 1 cubic centimeter.

Does density change when cut in half?

What happens to the density of an object if the object is cut in half? … The density remains the same because cutting the object in half will divide the mass & volume by the same amount. Also the density of a substance remains the same no matter what size it is.

Which has the greater density of an entire candy bar or a half candy bar?

2. Density is a ratio of weight or mass per volume and this ratio is greater for any amount of lead than for any amount of aluminum—see Table 5.1. 3. Both the half and the entire candy bar have the same density.

How does the density of gases at different elevations?

How does the density of gases at different elevations in the atmosphere differ from the density of liquids at different depths? Density of gases vary. The higher you are in the atmosphere the lower the density. … Is the value for atmospheric pressure at the surface of Earth constant?

What causes atmospheric pressure?

Air pressure is caused by the weight of the air molecules above. … This pressure causes air molecules at the Earth’s surface to be more tightly packed together than those that are high in the atmosphere.

What is the pressure of 1 atmosphere?

101 325 pascals

It corresponds to the pressure exerted by a vertical column of mercury (as in a barometer) 760 mm (29.9213 inches) high. One standard atmosphere which is also referred to as one atmosphere is equivalent to 101 325 pascals or newtons of force per square metre (approximately 14.7 pounds per square inch).

What will happen to the volume of a container if the gas is compressed?

During compression the volume (V) of a gas decreases. When this happens the pressure (P) of the gas increases if the number of moles (n) of gas remains constant. If you keep the pressure constant reducing the temperature (T) also causes the gas to compress.

What happens to the pressure inside of a container when the volume of a container of gas is reduced?

Because the volume has decreased the particles will collide more frequently with the walls of the container. Each time they collide with the walls they exert a force on them. More collisions mean more force so the pressure will increase. When the volume decreases the pressure increases.

What happens to the pressure if the gas volume is cut in half while N and T are held constant?

If volume increases then pressure decreases and vice versa when the temperature is held constant. Therefore when the volume is halved the pressure is doubled and if the volume is doubled the pressure is halved.

When air is compressed what happens to its density?

The air is compressed. The density increases as pressure increases. Altitude and weather systems can change the air’s pressure. As you go higher the air’s pressure decreases from around 1 000 millibars at sea level to 500 millibars at around 18 000 feet.

How much does air compress under pressure?

A gas will compress proportionately to the amount of pressure exerted on it. For example if you have a 1 cubic foot balloon and double the pressure on it it will be compressed to 1/2 cubic foot. Increase the pressure by 4 and the volume will drop to 1/4 the size etc.

When you heat a gas What happens?

Heating a gas increases the kinetic energy of the particles causing the gas to expand. In order to keep the pressure constant the volume of the container must be increased when a gas is heated.

What happens to the internal pressure in a fluid flowing in a pipe when its speed increases?

The internal pressure decreases in a fluid flowing through a horizontal pipe when its speed increases.

In which case is the pressure you exert on the floor the greatest?

The weight of the man is the same in all case so the pressure he exerts on the ground will be largest if the area in contact with the ground is the smallest.

When the speed of a fluid increases internal pressure in a fluid?

according to Bernoulli’s principle when the speed of a fluid increases internal pressure of the fluid decreases. This is a consequence of the conservation of energy.

What change in pressure occurs in a party balloon that is squeezed to one-third its volume with no change in temperature? The pressure will increase to three times its original pressure.

When an object is partially or wholly immersed in a liquid it is buoyed up?

Archimedes’ principle is named after Archimedes of Syracuse who first discovered this law in 212 B.C. Archimedes’ principle may be stated thus in terms of forces: Any object wholly or partially immersed in a fluid is buoyed up by a force equal to the weight of the fluid displaced by the object.

Is pressure greater or less in regions where streamlines are crowded?

Is pressure greater or less in regions where streamlines are crowded? Pressure is lower where streamlines are closer.

When you squeeze a balloon to make it smaller its density?

When you squeeze an air-field balloon you essentially compress the same amount of air into a smaller volume. Density ρ is inversely…

What happens to the volume of a loaf of bread that is squeezed?

What happens to the volume of a loaf of bread that is squeezed? … When the loaf of bread is squeezed the volume of the bread is reduced. Since mass remains the same a decrease in volume increases the density of the bread.
