Pressure In Gases (physics Only) (GCSE Physics)

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 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

Why are gases easier to compress than solids?

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

Absolute zero (0 K) is the temperature at which

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

Pressure = force ÷ area. If the same force acts on a smaller area, the pressure will

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

Which device measures atmospheric pressure?

Which is the best description of temperature in the particle model of matter?

A syringe with a fixed amount of air is pushed slowly so the plunger moves in and reduces the volume. The air temperature stays constant. The pressure inside the syringe
