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 \(P= \dfrac{2E}{3V}\). 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.
