15. With this type of lesson, the letters (A, B, C, D, etc.) Are randomized, so im sure the people who just gave the letters were right, but whereas No. 1 for them could've been A. Energy of Motion. For you, it could have been A. Stored energy. This means @Lily also knew this. Props to you 🙇🏼‍♀️

34. thermal energy unit 5 test
1) metal is heated from room temperature 200
2) The particles will have more space between them as a liquid, but at the same speed in both states.
3) the potential energy decreases due to the tighter arrangement of the particles.
4)an increase in heat and an increase in kinetic energy until a phase change occurs.
5)thermometer
6)4
7)convection
8) air moves from the areas of higher temperature to areas of lower temperature.
9)the temperature of the ice decreases, while the temperature of the water increases
