When a supply of hydrogen gas is held in a 4 liter container at 47°C it exerts a pressure

of 800 torr. The supply is moved to a 2000 mL container, and cooled to - 113°C. What is

the new pressure of the confined gas?

P₂ = 800 torr

Explanation:

Given dа ta:

Initial Volume = 4 L

Initial Temperature = 47°C (47+273 = 320 K)

Initial pressure = 800 torr

Final volume = 2000 mL (2000/1000 = 2 L)

Final temperature = - 113°C (-113+273 = 160 K)

Final pressure = ?

Solution:

Formula:

P₁V₁/T₁ = P₂V₂/T₂

P₁ = Initial pressure

V₁ = Initial volume

T₁ = Initial temperature

P₂ = Final pressure

V₂ = Final volume

T₂ = Final temperature

Solution:

P₂ = P₁V₁ T₂ / T₁ V₂

P₂ = 800 torr * 4 L * 160 K / 320 K * 2 L

P₂ = 512000 torr. L. K / 640 k. L

P₂ = 800 torr
