The mean free path of nitrogen molecules at 27°C is 3 × 10-7 m/s. if the average speed of nitrogen molecules at the same temperature is 600 m/s then the collision frequency will be |
Answer |
CP and CV denote the molar specific heats of a gas at constant pressure and at constant volume respectively. If $\dfrac{\text{C}_P}{\text{C}_V} = \gamma$ and CP – CV = R, then CV is equal to |
Answer |
The volume of a gas 20°C is 100cm3 at normal pressure. If its is heated to 100°C, its volume becomes 125 cm3 at the same pressure, then volume coefficient of the gas is (At normal pressure) |
