- 3. A type of thermodynamic system where the amount of energy within cannot change.
- 6. The amount of heat that must be added to one unit of mass of the substance in order to cause an increase of one unit in temperature.
- 8. Transfer of heat energy or electric charge through a material.
- 11. Energy that comes from a source and travels through space at the speed of light.
- 12. A system that does not have a net external force and does not exchange matter or energy with its surroundings.
- 13. The space between the atoms or molecules of the matter
- 15. Compressible fluid is a type of fluid that can change its volume under varying pressure, with air being a common example. Incompressible fluid is a type of fluid that cannot change its volume under varying pressure, with water being a common example.
- 16. An instrument used to measure and read temperature
- 18. Two or more atoms that are connected by chemical bonds where its structure and properties can be examined using physical methods.
- 20. A system that can exchange both energy and matter with its surroundings.
- 22. The physical process where matter moves from one state to another.
- 24. The amount of heat needed to cause a unit change in temperature in a given mass of material.
- 25. being or involving a state of matter dependent upon temperature.
- 29. the process in which the molecules are moved from the region of higher temperature to lower temperature.
- 30. The measurement of energy in a thermodynamic system.
- 31. A closed, 3D surface that encloses the system and separates it from its surroundings.

- 1. Expansion relationships for length, area, and volume of a body due to a change in temperature.
- 2. A measure of the disorder of a system. Entropy also describes how much energy is not available to do work.
- 4. The complete description of a physical system, referring to its condition at a particular moment in time.
- 5. The temperature does not change when energy is absorbed or released by a substance during a change in its physical state.
- 7. If the properties of the system like pressure, temperature, and volume stay in the same state over time and space.
- 9. The energy contained within a system that is responsible for its temperature.
- 10. The attractive forces between the negative end of one molecule and the positive end of another.
- 14. A system of matter and energy confined to a defined region of space that may exchange matter and energy with its surroundings.
- 15. The process of heat transfer by the bulk movement of molecules within fluids such as gasses and liquids.
- 17. The measure of hotness or coldness expressed in terms of any of several scales, including Fahrenheit and Celsius.
- 19. The combined energy from molecules moving, atoms vibrating, and the electric energy in molecules.
- 21. Energy that is in transit from a high temperature object to a lower temperature object.
- 23. Everything external to the system is the surroundings.
- 26. The chemical reactions in which heat energy is absorbed.
- 27. The position of a point in time on a cycle of a waveform. Phase is a dimensionless quantity.
- 28. Release of heat that causes the immediate surrounding temperature to rise.
