CE Four ideal gases have the following pressures, $P,$ volumes, $V$ and mole numbers, $n$ gas $A, P=100 \mathrm{kPa}, V=1 \mathrm{m}^{3}, n=10 \mathrm{mol}$ gas $\mathrm{B}, P=200 \mathrm{kPa}, V=2 \mathrm{m}^{3}, n=20 \mathrm{mol} ;$ gas $\mathrm{C}, P=50 \mathrm{kPa}$ $V=1 \mathrm{m}^{3}, n=50 \mathrm{mol} ;$ gas $\mathrm{D}, P=50 \mathrm{kPa}, V=4 \mathrm{m}^{3}, n=5 \mathrm{mol}$ . Rank these gases in order of increasing temperature. Indicate ties where appropriate.
