Thermochemistry

4. The change in the enthalpy of a chemical reaction that occurs at a constant pressure.
6. The property of matter which shows the capacity to perform work.
7. The heat absorbed by one mole of that substance as it is converted from a solid to a liquid.
8. The heat required to raise the temperature of the unit mass of a given substance by a given amount.
9. The process of measuring the amount of heat released or absorbed during a chemical reaction.
10. An apparatus for measuring the amount of heat involved in a chemical reaction or other process.
11. The energy possessed by an object due to its position relative to others
15. The enthalpy change when 1 mole of a substance burns and combines with oxygen.
17. A unit of energy equivalent to the heat energy needed to raise the temperature of 1 gram of water by 1 °C
18. The subsection of chemistry that deals with quantities of heat that gets absorbed or evolved during a chemical reaction.
19. Energy that is possessed by the process of being in motion.

1. The heat absorbed by one mole of a substance as it is converted from a liquid to a gas.
2. The net release of heat from a compound or reaction.
3. The energy stored in the Chemical bonds of a substance.
5. A physical quantity that expresses quantitatively the perceptions of hotness and coldness.
12. A quantity equivalent to the total heat content of a system
13. A law that states, “Energy can neither be created nor destroyed- only transformed from one form of energy to another.”
14. The SI unit of work or energy, equal to the work done by a force of one newton.
16. A form of energy arising from the random motion of the molecules of bodies, which may be transferred by conduction, convection, or radiation
20. The absorption of heat.
