PHYSICS IDEAL GAS LAW

1. If I heat air in an air balloon so that its Kelvin temperature doubles. The balloon has constant volume and pressure, so gas can get in and out through a hole. What happens to the mass of gas contained in the balloon?

2. Consider generally molecular oxygen and hydrogen mixed in air. Compare their average velocities:

In the initial state, an ideal gas has pressure p1, volume V1 and temperature T1. Now the gas changes its state by effecting a state change so that it reaches the pressure p2, the volume V2 and the temperature T2 in the new state. The pressure doubles during this state change, which is an isochore process. a) Find the work W performed during the isochore process. b) The heat Q is exchanged between the gas and the surroundings during the...

The volume of some air, assumed to be an ideal gas, in the cylinder of a car engine is 540cm3 at a pressure of 1.1 × 105Pa and a temperature of 27 °C. The air is suddenly compressed, so that no thermal energy enters or leaves the gas, to a volume of 30 cm3. The pressure rises to 6.5 × 106Pa. Determine the temperature of the gas after the compression.
