At a constant volume the specific heat of a gas is 0.075 and its molecular weight is $40.$ The gas is:

Options:

Answer:

Solution:

$q = \frac{c}{m} \Rightarrow C_{v} = q \times m = 0.075 \times 40 = 3.0 cal C_{P} - C_{v} = R C_{P} = C_{V} + R = 3 + 2 = 5 \frac{C _{P}}{C _{V}} = \frac{5}{3} = 1.66$ Monoatomic gas
