Pressure In Gases (physics Only) (GCSE Physics)

At higher altitudes the atmospheric pressure is lower because

A closed container of gas has pressure p and volume V. If the volume is reduced to V/4 at the same temperature, the pressure becomes

If the temperature of a fixed volume of gas is increased, the pressure usually

Why are gases easier to compress than solids?

A balloon is filled at sea level and then carried to a high mountain. If temperature stays constant the balloon’s internal pressure compared with the outside pressure will be

Which statement best describes Boyle’s law for a fixed mass of gas at constant temperature?

In the particle model, gas pressure depends on

A tyre gauge reads 220 kPa. This equals

A sealed rigid container holds a gas at 2.0 × 10^5 Pa. The container is heated so the gas pressure becomes 3.0 × 10^5 Pa. The factor by which the average kinetic energy of the particles changes is

A student measures gas pressure with a digital gauge and repeats the reading four times getting slightly different values. The small differences are called

A student uses a syringe and pressure gauge to show that when the plunger is pushed, pressure rises. This is best explained by
