You place air in a sealed can at standard temperature and pressure (STP). You double its absolute temperature (K) while leaving the volume constant. What happens to the pressure?

Verified Answer :

The pressure triples.

Answer:Pressure of the air inside the sealed container will get change 2 atm when absolute temperature is doubled.

Explanation:

According to question , Volume is constant

According to Gay Lussac's Law:

\(Pressure\propto Temperature\) (at constant temperature)

\(\frac{P_1}{T_1}=\frac{P_2}{T_2}\)

At STP, the temperature ,\(T_1=273 K\)

At STP, the pressure =\(P_1=1 atm\)

On doubling the absolute temperature the pressure changes \(P_2\):

On doubling the temperature= \(T_2=2\times T_1\)

\(P_2=\frac{1 atm\times 2\times 273 K}{273 K}=2 atm\)

Pressure of the air inside the sealed container will get change 2 atm when absolute temperature is doubled.
