Across
- 2. Amount of heat needed to change the temperature of 1 gram of water by 1 Celsius degree.
- 5. Measure of the hotness or coldness of substances, related to the average translational kinetic energy per molecule in a substance.
- 7. Total energy of the submicroscopic particles that make up a substance.
- 9. Measure of the energy dispersal of a system. Whenever energy freely transforms from one form into another, the direction of transformation is toward a state of greater disorder and, therefore, toward greater entropy.
- 10. Transfer of thermal energy in a gas or liquid by means of currents in the heated fluid.
Down
- 1. Lowest possible temperature that a substance may have-the temperature at which molecules of the substance have their minimum kinetic energy.
- 3. Transfer of thermal energy by molecular and electronic collisions within a substance.
- 4. Transfer of energy by means of electromagnetic waves.
- 6. study of heat and its transformation into different forms of energy.
- 8. Thermal energy that flows from a substance of higher temperature to a substance of lower temperature.
