Answer:
P₂ = 0.11 atm
Explanation:
Given data:
Initial pressure = 0.12 atm
Initial temperature = 294 K
Final pressure = ?
Final temperature = 273 K
Solution:
According to Gay-Lussac Law,
The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.
Mathematical relationship:
P₁/T₁ = P₂/T₂
Now we will put the values in formula:
0.12 atm / 294 K = P₂/273 K
P₂ = 0.12 atm × 273 K / 294 K
P₂ = 32.76 atm. K /294 K
P₂ = 0.11 atm
