T is the temperature of a fixed mass of gas (K) Explain, using the kinetic theory of particles, what happens to the particles in a liquid when it melts and becomes a gas. Explain, using kinetic theory, how the air in a bicycle tyre creates pressure on the inside surface of the tyre. Why does the Kelvin temperature scale start at -273 °C? Convert these temperatures from degrees Celsius to Kelvin. 0 °C 20 °C -273 °C 100 °C A conical flask is sealed with air inside, and is placed in a heat bath. The temperature of the gas increases from 20 °C to 70°C. After every 10 °C temperature increase, the pressure of the gas is measured using a Bourdon gauge. The results are shown. Temperature / °C Pressure / x 105 Pa 20 1.01 30 1.04 40 1.08 50 1.11 60 1.15 70 1.18
