How does the density of air change when it is compressed to half its original volume?

By how much does the density of air increase when it is compressed to half its volume? Density is inversely proportional to volume, so the density of air doubles when it is compressed to half its volume.

What will happen to the pressure when the volume of the gas was halved?

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.

What will happen to the pressure if the volume is decreased by half and the temperature is doubled?

The law itself can be stated as follows: for a fixed amount of an ideal gas kept at a fixed temperature, P (pressure) and V (volume) are inversely proportional—that is, when one doubles, the other is reduced by half. The moving wall converts the effect of molecular collisions into pressure and acts as a pressure gauge.

What happens to the volume of a gas during compression?

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 when you compress a balloon?

This is because the air in the balloon is compressed from the pressure when submerged, but returns to its normal size and pressure when it returns to the surface. This is because the pressure has pushed the air molecules closer together.

What happens to the pressure when the volume of an ideal gas is doubled while the temperature is halved?

Thus, doubling the Kelvin temperature and halving the pressure quadruples the volume.

What happens to the pressure of a gas if its volume is decreased by half its original size at constant temperature?

Another way of thinking about this law is that the values of pressure and volume are inversely proportional; if one goes up, the other must decrease by the same factor. If you trap gas in a cylinder, and then reduce the internal volume of the cylinder to half its original value, the pressure will double.

Does gas heat up when compressed?

Originally Answered: Why does compressed air create heat? In air (or any gas) there are molecules moving around constantly and collide with each other in the process. This inter-collision between air molecules increases on compression which produces heat.

When you inflate a balloon its volume?

What do you think happens to the volume of gas inside the balloon? As the temperature increases, the gas particles absorb more heat energy. They speed up and move farther away from one another. So the increase in temperature causes an increase in volume.
