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

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

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

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

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 fixed mass of gas in a rigid container has pressure 2.0 × 10^5 Pa at 400 K. What will the pressure be if the temperature is reduced to 200 K (ideal gas 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 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?
