This question is about the thermal properties and pressure of gases.
A sample of gas is heated inside a rigid, sealed research canister with a constant volume.
Which statement correctly describes the behaviour of the gas molecules?
Describe what happens to the average kinetic energy of the gas molecules as the temperature of the gas is reduced from 400 K400\text{ K}400 K down to 150 K150\text{ K}150 K.
Convert a temperature of −23 ∘C-23\ ^\circ\text{C}−23 ∘C into kelvin (K).
The gas inside the canister has a pressure of 120 kPa120\text{ kPa}120 kPa at a temperature of −23 ∘C-23\ ^\circ\text{C}−23 ∘C. Calculate the new pressure of the gas when its temperature rises to 127 ∘C127\ ^\circ\text{C}127 ∘C.
