Problem

An airtight steel tank contains

1.20\,\text{m}^3

of an ideal gas at an absolute pressure of

1.00\times10^{5}\,\text{Pa}

and a temperature of

320\,\text{K}

. The gas is compressed to

80\%

of its original volume, and during the compression its absolute temperature rises by

10\%

. (a) Determine the new pressure of the gas after compression. (b) By what percentage has the pressure changed from its initial value? Show your working clearly.
