Across
- 2. A branch of chemistry that studies the heat transfer associated with chemical reactions and physical changes of state
- 5. A unit of energy which is equal to Newtons.
- 8. The area around the substance that is absorbing or releasing the heat.
- 11. A chemical reaction in which its products absorb energy.
- 12. A measure of how much energy is needed to raise 1 gram of the substance by 1 degree celsius.
- 14. A visual representation of energy in a chemical reaction. Reactants are shown on the left side and products are shown on the right.
- 15. The ability of an object to transfer heat from one part of itself to another by conduction. This is a result of atomic or molecular motion.
Down
- 1. A chemical reaction in which energy is released into the surroundings.
- 3. A form of energy related to the motion of atoms and molecules. It can be transferred by conduction, convection, or radiation.
- 4. The transfer and distribution of heat energy from atom to atom within a material, such as copper wire or a frying pan.
- 6. The substance that is absorbing or releasing the heat.
- 7. Electromagnetic waves that directly transport energy in all directions through space.
- 9. An extensive property that is a measure of the average kinetic energy of molecules and atoms. It determines the spontaneous heat flow, which is always from hot to cold.
- 10. Amount of heat needed to raise the temperature of one gram of water by one degree Celsius.
- 13. The transfer of heat by the physical motion of masses of fluid (liquids and gases) by changes in density of the fluid
