(adsbygoogle = window.adsbygoogle || []).push({}); HW Help: Absolute temp and ideal gas law

1. The problem statement, all variables and given/known data

What fraction of the air molecules in a house must be pushed outside while the furnace raises the inside temperature from 16C to 20C? The pressure does not change since the house is not 100% airtight.

2. Relevant equations

PV=NkT

PV/T=PV/T

???

3. The attempt at a solution

NkT=NkT? N2/N1 = T2/T1. N2 = .80N1. Answer provided is .0136. I can't figure how that answer comes about. Help would be grateful. Thanks.
