A compressor takes 0.50 m3 of a gas at 33°C and 760 mm Hg and compresses it to 0.10 m3, cooling it to -55°C at the same time. Wh
weqwewe [10]

The pressure of the gas is 2700 mmHg.

To solve this problem, we can use the <em>Combined Gas Laws</em>:

(<em>p</em>_1<em>V</em>_1)/<em>T</em>_1 = (<em>p</em>_2<em>V</em>_2)/<em>T</em>_2

<em>p</em>_2 = <em>p</em>_1 ×<em> V</em>_1/<em>V</em>_2 × <em>T</em>_2/<em>T</em>_1

<em>T</em>_2 = (-55+273.15) K = 218.15 K; <em>T</em>_1 = (33+273.15) K = 306.15 K

<em>p</em>2 = 760 mmHg × (0.50 m^3/0.10 m^3) × (218.15 K/306.15 K) = 2700 mmHg
