The temperature of a fixed mass of gas at constant volume is increased. State and explain, in terms of particles, how the pressure of the gas changes.
State the value of absolute zero in ∘C^\circ\text{C}∘C.
Explain what is meant by the term absolute zero. Refer to particles in your answer.
Cylinder 1 contains 400 cm3 of gas at a pressure of 1.5 × 105 Pa. The gas is transferred to cylinder 2 and the pressure increases to 2.5 × 105 Pa. The temperature remains constant. Calculate the volume of cylinder 2.
