Question 18

A fixed mass of nitrogen gas is compressed inside a cylinder, with no change in temperature.

The table below shows the pressure $P_1\,$ and volume $V_1\,$ before the gas is compressed, and the volume $V_2\,$ after the gas is compressed.

	pressure in kPa	volume in $m3\text{m}^3$
before the gas is compressed	$P_1 = 140$	$V_1 = 1.6$
after the gas is compressed	$P_2 =$	$V_2 = 0.40$

Calculate the pressure $P_2\,$ after the gas is compressed. Use the equation:

P_2 = \frac{P_1 \times V_1}{V_2}
