Thermodynamics Physics

2. Property depending on the size/extent of the system.
4. A system with no exchange of matter or energy.
7. Two primary modes of energy transfer in a system.
12. Change in enthalpy when one mole of substance combusts completely.
13. Energy available to do work in a system at constant temperature and pressure.
16. Exchange of energy between a system and its surroundings.
21. A property depending only on the current state, not the path taken.
22. Property independent of the size of the system.
24. General tendency of entropy to increase in isolated systems.
26. Process occurring spontaneously, creating entropy.
27. Reference condition for thermodynamic measurements.
28. Idealized process occurring infinitely slowly, maintaining equilibrium.
29. A system allowing the exchange of matter and energy with surroundings.
30. Condition where macroscopic properties remain constant over time.

1. Change between solid, liquid, and gaseous states of matter.
3. Properties defining the macroscopic state of a system.
5. Heat exchange at constant pressure during a reaction.
6. A process that can reverse with no net energy change.
8. A concept describing a system interacting with its surroundings.
9. Measure of disorder or randomness in a system.
10. A law stating total enthalpy change is independent of the reaction path.
11. Energy driving chemical reactions towards equilibrium.
14. Dependence of reaction feasibility on temperature.
15. Total energy contained in a system, including kinetic and potential energy.
17. A process requiring external energy input to occur.
18. Principle that energy cannot be created or destroyed.
19. Process occurring without external energy input.
20. Constant characterizing equilibrium concentrations of products and reactants.
23. Change in enthalpy when one mole of a compound forms.
25. A system allowing only energy exchange, not matter.
