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

. The gas occupies

0.015\,\text{m}^3

290\,\text{K}

. It is first heated at the same pressure to

380\,\text{K}

and is then cooled, still at the same pressure, until its volume becomes

0.012\,\text{m}^3

. (a) Calculate the volume of the gas immediately after it has been heated to

380\,\text{K}

. (b) Determine the temperature of the gas when its volume is

0.012\,\text{m}^3

at this pressure. (c) Find the percentage change in temperature between the initial state (

290\,\text{K}

) and the final state found in part (b).
