Question

If a gas in a jar with a leaky seal is heated so that kevin temperature quadruples, what fraction of the moles of gas escape?

Answer 1

Step-by-step explanation:

From ideal gas equation we have

P1V1= n1RT1

at state 1

And

P2V2= n2RT2

at state 2

given the volume and pressure as constant

therefore we can write

n1/n2 = T2/T1

n2/n1 = T1/T2 = 1/4

Therefore the fraction of moles of gas escaped = 1-1/4 = 3/4
