Approximated as a saturated liquid at a given temperature 9. The property value that is size dependent 10. Internal energy associated with the kinetic energy of the molecules 13. There are no unbalanced potentials within the system 18. The disordered tendency of the 2nd law of Thermodynamics 19. The process by which heat energy is transmitted through collisions between neighboring molecules. 20. The transmission of energy in the form of waves or particles through space 21. Thermodynamic quantity equivalent to the total heat content of a system 22. A type of a source of energy 24. Internal energy associated with the phase of a system 25. This is also known as a compressed liquid

Down 2. The energy principle of the 1st Law of Thermodynamics 3. A type of boundary of a system 4. A system with fixed non-changing mass of fluid but with energy exchange 7.
