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.
A cylinder contains 450 cm3450\text{ cm}^3450 cm3 of gas at a pressure of 1.2×105 Pa1.2 \times 10^5\text{ Pa}1.2×105 Pa. The gas is transferred to a second cylinder, and its pressure decreases to 8.0×104 Pa8.0 \times 10^4\text{ Pa}8.0×104 Pa while the temperature remains constant.
Calculate the volume of the second cylinder.
