A gas at

27^\circ\text{C}

in a cylinder has a volume of

4\,\text{L}

and pressure

100\,\text{N m}^{-2}

. (i) The gas is first compressed at constant temperature until its pressure is

150\,\text{N m}^{-2}

. Calculate the change in volume. (ii) It is then heated at constant volume until its temperature becomes

127^\circ\text{C}

. Calculate the new pressure.
