Across
- 2. degree of ------(the number of ways a molecule in the gas phase may move, rotate, or vibrate in space)
- 4. effect change in apparent frequency of sound when there is relative motion between source and the observer
- 6. tendency of a force to rotate a body about any axis
- 9. process takes place at constant pressure
- 10. heat flow per second per unit area per unit temperature gradient when heat flows normally to an area inside the material
- 11. the energy is shared equally between the different degrees of freedom and each degree of freedom of a molecule has an average of energy equal to 1/2 kT
- 12. ratio of tensile stress to the tensile strain if the proportionality limit is not been exceeded
Down
- 1. square of this is directly proportional to cube of distance between two bodies
- 3. transfer of energy from one object to another as a result of a difference in temperature
- 5. first law of -------------- (The change in internal energy of a closed system will be equal to the heat added to the system minus the work done by the system
- 7. property of an object to resist any rotational motion
- 8. minimum velocity required by body to overcome planet's gravitational pull to leave the planet and travels into the space
