Increasing The Pressure Of A Gas (physics Only) (ht Only) (GCSE Physics)

A sample of ideal gas at 1.5 × 10^5 Pa is heated at fixed volume so its pressure rises to 3.0 × 10^5 Pa. If initial absolute temperature was 290 K, what is the final temperature?

A syringe containing air is compressed slowly keeping temperature constant. According to the particle model, why does the measured pressure increase?

A sealed syringe initially at room temperature contains gas at pressure P0. The syringe is plunged quickly to half its initial volume so the process is near-adiabatic. If the mean kinetic energy per particle increases due to compression, which of these increases?

A piston contains gas at 100 kPa and 300 K. If the number of gas moles is doubled rapidly while keeping volume constant and no heat exchange, which immediate effect will be observed?

Which microscopic change best explains why adding more gas molecules (same T, same volume) increases pressure?

A sample of gas obeys PV = nRT. If you double n and double V while holding T constant, what happens to pressure P?

A container of gas has movable piston. Which single action increases pressure while keeping the number of moles constant and without changing temperature?

During an experiment at constant volume, the pressure of a gas is observed to increase linearly with absolute temperature. Which law does this observation illustrate?

Which particle-level change explains why increasing temperature at constant volume raises pressure?

A student compresses a gas slowly so heat can escape and temperature stays constant (isothermal). A second student compresses an identical gas quickly so heat does not escape and temperature rises (adiabatic-like). Which student will measure the higher final pressure for the same final volume?

In the particle model, why does reducing the volume of a gas (with the same number of particles and same temperature) increase its pressure?
