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

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?

For a fixed mass of gas in a sealed container, which two independent changes would both increase the internal pressure?

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?

When compressing a gas, which of the following reduces the risk of overheating the gas and causing material failure in a container?

Which statement correctly describes how a fire piston ignites tinder when the plunger is pushed quickly?

A container of gas is divided by a removable partition. The two sides have equal volume and equal pressure. If the partition is removed, allowing the gases to mix, what is the pressure in the final single volume (assuming same temperature and ideal behaviour)?

A container holds gas at pressure P. You halve the surface area of one wall while keeping the same net force on that wall. What happens to the measured pressure on that wall?

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

A sealed container of gas at equilibrium has particles hitting each wall with average force f per collision and collision rate r per unit area. Which change increases the pressure most effectively, assuming you can only change one variable?

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

A piston contains 1.00 mol of ideal gas at 1.00 × 10^5 Pa and 300 K. If the temperature is raised to 600 K at constant moles and constant volume, what happens to the pressure?
