Question

1. heat will always transfer thermal energy from __ to __. a) hot to cold b) cold to hot c) endothermic to exothermic 18) which state of water would have the highest thermal energy? a) ice b) liquid water c) water vapor

Explanation:

1. According to the second - law of thermodynamics, heat transfer occurs spontaneously from a region of higher temperature (hot) to a region of lower temperature (cold).
2. The state of matter with the highest thermal energy is the one with the highest kinetic energy of its particles. Water vapor has the highest kinetic energy among ice, liquid water, and water vapor as its particles are moving freely and at high speeds.

Answer:

1. a) Hot to cold
2. c) Water vapor
