1. True

2. True

3. False

4. True

5. True

3. Heat can be thought of as the movement of particles (molecules etc). The faster they move the hotter things are. Energy of movement is called kinetic energy. Temperature is a measure of the average kinetic energy of the particles, while thermal energy is the total kinetic energy of the particles.
