Marks: +1, -0

Two gases A and B with their molecular weights 28 and 44 respectively, expand at constant pressures through the same temperature range.
The ratio of quantity of work done by the two gases (A : B) is__________.

7 : 11
11 : 7
4 : 11
7 : 4

Solution:

The work done by gas is inversely proportional to its molecular mass.

(W_A/W_B) = (M_B/M_A)

= (44/28) = (11/7)
