QAIPM-2015-Ph-1228: NEET 2015 Physics - Class 11 AIPM-2015-Ph-1228 Solution: 4.0 g of a gas occupies 22.4 litres at NTP. The specific heat…

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 J K−1 mol−15.0\ \text{J K}^{-1}\ \text{mol}^{-1}. If the speed of sound in this gas at NTP is 952 m s−1952\ \text{m s}^{-1} then the heat capacity at constant pressure is (Take gas constant R = 8.3 J K−1 mol−18.3\ \text{J K}^{-1}\ \text{mol}^{-1}) 7.0 J K−1 mol−17.0\ \text{J K}^{-1}\ \text{mol}^{-1} 8.5 J K−1 mol−18.5\ \text{J K}^{-1}\ \text{mol}^{-1} 8.0 J K−1 mol−18.0\ \text{J K}^{-1}\ \text{mol}^{-1} 7.5 J K−1 mol−17.5\ \text{J K}^{-1}\ \text{mol}^{-1}
