Select the correct statement.
- A The product of pressure and volume of an ideal gas will be equal to translational kinetic energy of the molecules.
- B The temperature of gas is \(-73^{\circ} \mathrm{C}\). When the gas is heated to \(527^{\circ} \mathrm{C}\), the r.m.s. speed of the molecules is doubled.
- C The temperature of gas is \(-100^{\circ} \mathrm{C}\). When the gas is heated to \(+627^{\circ} \mathrm{C}\), the r.m.s. speed of the molecules is four times.
- D The product of pressure and volume of an ideal gas will be equal to half the translational kinetic energy.
Answer & Solution
Correct Answer
(B) The temperature of gas is \(-73^{\circ} \mathrm{C}\). When the gas is heated to \(527^{\circ} \mathrm{C}\), the r.m.s. speed of the molecules is doubled.
Step-by-step Solution
Detailed explanation
\(T_1 = -73^{\circ} \mathrm{C} = 200 \mathrm{~K}\) \(T_2 = 527^{\circ} \mathrm{C} = 800 \mathrm{~K}\)
