Question

for each example, determine whether the substance has high thermal energy (a) or low thermal energy (b).

1. __ molten metal
2. __ frozen food
3. __ lava
4. __ the sun
5. __ snow
6. __ deep ocean water
7. __ fire
8. __ air in antarctica
9. __ steam
10. __ ice cubes
11. __ glacier
12. __ boiling cooking oil

for each example, draw arrows to represent the movement of thermal energy from one substance to another

Explanation:

• Thermal energy is related to the temperature of a substance. Higher - temperature substances generally have higher thermal energy.
• Molten metal, lava, the Sun, fire, steam, and boiling cooking oil are at high temperatures, so they have high thermal energy (A).
• Frozen food, snow, deep ocean water, air in Antarctica, ice cubes, and glaciers are at low temperatures, so they have low thermal energy (B).
