Q. No.Which of the following parameters is the same for molecules of all gases at a given temperature?
| 1. | mass | 2. | speed |
| 3. | momentum | 4. | kinetic energy |
The pressure of an ideal gas is written as \(P= \frac{2E}{3V}\). Here \(E\) refers to:
| 1. | translational kinetic energy |
| 2. | rotational kinetic energy |
| 3. | vibrational kinetic energy |
| 4. | total kinetic energy |
The energy of a given sample of an ideal gas depends only on its:
1. volume
2. pressure
3. density
4. temperature.
