Question

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

Answer 1

Answer:

P₂ = 800 torr

Explanation:

Given data:

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
