What happens to the volume if the pressure is doubled?

FIGURE 9.8 Boyle’s Law: At constant temperature, the volume of a gas sample is inversely proportional to the pressure. If the pressure on the piston is doubled, the volume of the gas decreases by one-half.

Which action causes the volume of a gas sample to increase?

When a gas sample at a constant pressure is heated, its volume increases because the molecules are moving faster and bumping into container walls with more momentum therefore pushing out harder.

What happens to the volume of gas when the amount of the gas doubles?

According to the Boyle’s law, If pressure doubles, volume should be halved. If you consider initial pressure and volume as P1 and V1, applying…

What happens if the volume doubles?

In other words, pressure is inversely proportional to volume. So, if you double the volume, it will be like halving the pressure. This also makes sense if you think about it logically. If the gas has more space to move around in, it’s going to spend less time pressing against the walls of the container.

Why does volume of a gas decrease with increase of pressure?

The reduction in the volume of the gas means that the molecules are striking the walls more often increasing the pressure, and conversely if the volume increases the distance the molecules must travel to strike the walls increases and they hit the walls less often thus decreasing the pressure.

Why will a gas at a higher temperature occupy a larger volume at a constant pressure answer in terms of collisions speed of particles number of collisions?

If the temperature is increased, the average speed and kinetic energy of the gas molecules increase. If the volume is held constant, the increased speed of the gas molecules results in more frequent and more forceful collisions with the walls of the container, therefore increasing the pressure (Figure 1).

How is the volume of a gas related to its concentration of particles?

Pressure will compress a gas, reducing its volume and giving it a greater density and concentration of particles. Pressure will accelerate a gas, extending its volume and allowing a smaller density and concentration of particles.
