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

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

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)?

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 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?

Which of the following will increase the frequency of molecule–wall collisions in a confined gas?

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

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

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?

Which experimental change will NOT increase the pressure of a fixed amount of gas in a rigid vessel?

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

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)?
