Across
- 3. The study of heat and its transformation into different forms of energy.
- 5. The transfer of thermal energy in a gas or liquid by means of currents in the heated fluid. The fluid flows, carrying energy with it.
- 6. The amount of heat needed to change the temperature of 1 gram of water by celcius degree
- 8. The transfer of thermal energy by molecular and electronic collisions within a substance (especially within a solid).
- 10. The quantity of heat required to raise the temperature of a unit mass of a substance by 1 degree Celcius
Down
- 1. No system can reach absolute zero
- 2. A measure of the hotness or coldness of substances, related to the average translational kinetic energy per molecule in a substance; measured in degrees Celcius, in degrees Fahrenheit, or in kelvins.
- 4. The lowest possible temperature that a substance may have, the temperatureat which molecules of the substance have their minimum kinetic energy.
- 7. The transfer of energy by means of electromagnetic waves.
- 9. The thermal energy that flows from a substance of higher temperature, commonly measured in calories or joules.
