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

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?

Which expression (ideal-gas form) correctly links pressure P, volume V, number of moles n and absolute temperature T?

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

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

Which statement describes why rapid compression (faster than thermal losses) produces a higher peak pressure than slow compression to the same final volume?

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?

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 ideal gas at 2.0 × 10^5 Pa and 0.50 m^3. Moles held constant. If the piston is suddenly released and the gas expands to 1.0 m^3 adiabatically so temperature drops, which of these must be true immediately after expansion?

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?

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?

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