Thermal Energy and Matter
Directions: On the line before each statement, write T if the statement is true or F if the statement is false.
T 1. When a material gains thermal energy and melts, it is undergoing a physical
change.
2. Heating causes a substance to lose thermal energy.
3. When a material is heated, its particles move closer together.
4. When a material loses thermal energy, it usually contracts.
T 5. A temperature of 0°F is equal to 32°C.
T 6. Water boils at 100°C.
7. During a change of state, the thermal energy gained or lost by a material
changes the kinetic energy of its particles.
8. The melting point of gold is more than 1,000°C.
9. A material’s melting point and freezing point are the same.
10. Vaporization that occurs at the surface of a liquid is called evaporation.
11. The change from a gas to a liquid is condensation.
12. A change of state directly from a gas to a solid is known as sublimation.
