At a constant volume the specific heat of a gas is 0.075 and its molecular weight is 40.40. The gas is:

Options

  1. AMonoatomic
  2. BDiatomic
  3. CTriatomic
  4. DNone of these

Correct answer

A. Monoatomic

Step-by-step solution

q=cm⇒Cv=q×m=0.075×40=3.0calCP−Cv=RCP=CV+R=3+2=5CPCV=53=1.66\begin{aligned} & q=\frac{c}{m} \\ & \Rightarrow C_{v}=q \times m \\ &=0.075 \times 40 \\ &=3.0 \mathrm{cal} \\ & C_{P}-C_{v}=R \\ & C_{P}=C_{V}+R \\ &=3+2=5 \\ & \frac{C_{P}}{C_{V}}=\frac{5}{3}=1.66 \end{aligned} Monoatomic gas
