An open flask contains air at 27 °C temperature and one atm pressure. The flask is heated to 127 °C at the same pressure. What fraction of the original air will remain in the flask?
A.2/5th
B.2/3rd
C.2/7th
Explanation
Open container means, P and V is constant. 1 1 2 2 T = const T = T n n n >> 1 2 300 = 400 n n x x 2 1 3 = 4 n n
