Thermochemistry vocab

3. is the science or act of measuring changes in state variables of a body for the purpose of deriving the heat transfer associated with changes of its state due
4. Heat, the heat required to raise the temperature of the unit mass of a given substance by a given amount
6. unit of work or energy in the International System of Units (SI); it is equal to the work done by a force of one newton acting through one metre
7. A measurement of the energy content of food.
8. the average kinetic energy of all the atoms or molecules of that substance
11. the heat absorbed by one mole of that substance as it is converted from a liquid to a gas
13. thermal energy transferred between two systems at different temperatures that come in contact.
16. energy which a body possesses by virtue of being in motion.
17. the branch of chemistry concerned with the quantities of heat evolved or absorbed during chemical reactions.
18. a thermodynamic quantity equivalent to the total heat content of a system. It is equal to the internal energy of the system plus the product of pressure and volume.
19. the amount of energy is neither created nor destroyed.
20. Chemical reactions that absorb (or use) energy

1. an apparatus for measuring the amount of heat involved in a chemical reaction or other process.
2. is the difference between total reactant and total product molar enthalpies, calculated for substances in their standard states.
5. the energy stored in the chemical bonds of a substance.
9. Chemical reactions that release energy
10. the heat absorbed by one mole of that substance as it is converted from a solid to a liquid
12. the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.
14. the heat energy given out when one mole of a substance burns completely in oxygen.
15. power derived from the utilization of physical or chemical resources, especially to provide light and heat or to work machines.
