Across
- 1. The change in heat during a chemical reaction at constant pressure.
- 8. The total heat content change in a system at constant pressure.
- 11. A reference state for a substance used to calculate its properties under different conditions.
- 12. The pressure exerted by a single component in a mixture of gases.
- 13. The change in enthalpy when a reaction occurs at constant pressure.
- 15. The movement of heat energy from one object to another.
- 17. The change in entropy when a process occurs.

Down
- 2. A number that expresses the relationship between products and reactants at equilibrium.
- 3. The potential energy of molecules which drives chemical reactions.
- 4. The interface separating a system from its surroundings.

- 6. energy A thermodynamic quantity that measures the useful work obtainable from a system.
- 7. A property whose value does not depend on the path taken to reach that specific value.
- 9. A process that cannot return the system to its original state.
- 10. The total energy contained within a system.
- 14. A condition where all parts of a system are at the same temperature.
- 16. The principle that the total energy of an isolated system remains constant.

- 28. A principle stating that energy cannot be created or destroyed, only transformed.
