Question

a bottle is heated with mouth open to have a final temperature as
125c from its original value of 25c the mole percentage of expelled
air is about a)50% b)25% c)33% give ans with explanation

As we know
PV = nRT
â€‹From the above relation we know that
temperature of gas is inversely proportional to the number of
moles

T1T2=n2n1298398=n2n11-298398=1-n2n1100398=n1-n2n10 2512=n1-n2n1

Fraction of expelled air is 0 2512
% Fraction of expelled air is 25 12

a bottle is heated with mouth open to have a final temperature as 125c from its original value of 25c .the mole percentage of expelled air is about a)50% b)25% c)33% give ans. with explanation
