Question

A gas 'X' at 150 degrees celsius is heated until its pressure doubles and volume triples from the original pressure and volume. If the original volume is 1000cc., calculate the temperature to which it should be heated​

Answer 1

Answer:

Using gas equation, we have

(P1*V1) /T1=(P2*V2) /T2 where P=Pressure, V=Volume and T=Absolute temperature of the gas.

Given, P1=P2=P(say) (Since pressure is constant)

V1=V(say), where V is the initial volume of the gas.

Therefore, V2=2V since final volume is double the initial volume.

T1=(27+273)K=300K

T2=?

Substituting the values obtained,in the gas equation, we have

P*V/300=P*2V/T2

Solving, we get T2=final temperature of the gas=600K or (600–273)degree C or 327 degrees C.
