(a) A car tyre has a fixed internal volume of 0.0120 m3. On a day when
the temperature is 25 degC the pressure in the tyre has to be
increased from 2.62 X 10^5 Pa to 3.23 X 10^5 Pa. Assuming the air is
an ideal gas, calculate the amount of air which has to be supplied at
constant temperature.
(b) Apply the first law of thermodynamics to the pressure increase in
(a) in order to calculate the amount of work which has to be done to
increase the pressure.
