- 1. the energy is stored in the chemical bonds of a substance.
- 5. A unit of energy equivalent to the heat energy needed to raise the temperature of 1 gram of water by 1 °C
- 7. used to measure amounts of heat transferred to or from a substance.
- 10. characterized by or formed with absorption of heat.
- 11. characterized by or formed with evolution of heat.
- 12. the heat required to raise the temperature of the unit mass of a given substance by a given amount
- 13. the heat absorbed by one mole of that substance as it is converted from a solid to a liquid.
- 15. the SI unit of work or energy, equal to the work done by a force of one newton when its point of application moves one meter in the direction of action of the force
- 17. power derived from the utilization of physical or chemical resources, especially to provide light and heat or to work machines.
- 18. the transfer of kinetic energy from one medium or object to another, or from an energy source to a medium or object
- 19. the amount of heat that must be added or removed during a chemical reaction in order to keep all of the substances present at the same temperature.
- 20. 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.
