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
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) |
Answer |
The kinetic energy of one gm-molecule of a gas at normal temperature and pressure is (R = 8.31 J/mol-K) |
Answer |
One mole of mono atomic gas (γ = 5/3) is mixed with one mole of diatomic gas (γ = 7/5) what will be the value of γ for the mixture? |
Answer |
The r.m.s velocity of the molecules of an ideal gas is C at a temperature of 100 K. at what temperature is r.m.s. velocity will be doubled? |
Answer |
The r.m.s. speed of the molecules of an enclosed gas is $x$. what will be the r.m.s. speed, if the pressure of the gas is doubled but the temperature is kept constant? |
Answer |
The r.m.s. velocity of the molecules in the sample of helium is 5/7th that of the molecules in the sample of hydrogen. If the temperature of the hydrogen sample is 0°C that of helium is |
Answer |
