Answer:
False
Explanation:
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
P₁ = Initial pressure
T₁ = Initial temperature
P₂ = Final pressure
T₂ = Final temperature
Now consider that at temperature of 10°C pressure was 6 atm. When temperature is increases to 30°C the pressure will be,
Initial temperature = 10 + 273 = 283 K
Final temperature = 30 + 273 = 303 K
Initial pressure = 6 atm
Final pressure = ?
Now we will put the values in formula:
6 atm / 283 K = P₂/303 K
P₂ = 6 atm × 303 K / 283 K
P₂ = 1818 atm. K /283 K
P₂ = 6.4 atm
So pressure will increase by increasing the temperature.
