Question

When a supply of hydrogen gas is held in a 4 liter container at 320 K it exerts a pressure of 800 torr. The supply is moved to a 2 liter container, and cooled to 160 K. What is the new pressure of the confined gas?

Answer 1

The answer is 1.05atm.Here it is

Answer 2

Answer:

The pressure on the confined gas is 800 torr.

Explanation:

Given is the supply of hydrogen gas in a 4L container at a temperature of 320K. The gas exerts a pressure of 800 torr.

When the gas is shifted to a new container of 2L volume and kept at 160K temperature the pressure on the confined gas is  $P_{gas}$

Using Ideal Gas equation,

$\frac{PV}{T}=constant$

$\frac{800\times4}{320}=\frac{P_{gas}\times2 }{160}$

$P_{gas}=800 torr$

Hence, the pressure on the confined gas is 800 torr.
