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

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

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

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 cylinder of gas is heated at constant volume so the pressure increases from 120 kPa to 180 kPa. By what factor has the absolute temperature changed?

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

A sealed rigid container holds a fixed mass of an ideal gas. Which single change will increase the gas pressure inside the container?

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

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

A fixed mass of gas at 300 K and 100 kPa is compressed isothermally to half its original volume. What is its new pressure (ideal behaviour assumed)?

A fixed mass of gas is heated in a constant-volume steel container that can safely hold pressure up to 5.0 × 10^6 Pa. Initial pressure 1.0 × 10^5 Pa, initial temperature 290 K. Using ideal gas law, what maximum temperature T_max (in K) would cause pressure to reach 5.0 × 10^6 Pa (approximate)?

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?
