1.	`4.0 g` of a gas occupies `22.4` litres at NTP. The specific heat capacity of the gas at constant volume is `5.0 JK^(-1)mol^(-1)`. If the speed of sound in this gas at NTP is `952 ms^(-1)`. Then the heat capacity at constant pressure isA. `8.5 JK^(-1) mol^(-1)`B. `8.0 JK^(-1) mol^(-1)`C. `7.5 JK^(-1) mol^(-1)`D. `7.0 JK^(-1) mol^(-1)`
Answer» Correct Answer - B Speed of sound `V = sqrt((gammaRT)/(M))` `V = sqrt((C_P)/(C_v)(RT)/(M))` `952=sqrt((C_(P)xx8.3xx273)/(5xx4xx10^(-3))` `C_(p)=8JK^(-1) mol^(-1)`.
