Question

Two identical containers, each of volume V 0 ​ , joined by a small pipe hold the same gas at pressure p 0 ​ and temperature T 0 ​ . One is kept at T 0 ​ and the other is heated to 3 T 0 ​ . The number of moles in the container at 3 T 0 ​ is:

TestHub · Accepted Answer

Moles are conserved: R T 0 ​ 2 p 0 ​ V ​ = R T 0 ​ p V ​ + 3 R T 0 ​ p V ​ = 3 R T 0 ​ 4 p V ​ . So p = 2 3 ​ p 0 ​ . A. n = R ( 3 T 0 ​ ) p V 0 ​ ​ = 3 R T 0 ​ 2 3 ​ p 0 ​ V 0 ​ ​ = 2 R T 0 ​ p 0 ​ V 0 ​ ​ . A.
