Answer:
1. Raises the temperature. 2. Increases volume.
When heat energy is added to a substance, this results in an increase in the kinetic energy of its particles, that is, the particles move at higher speeds. Since temperature is a measure of the average kinetic energy, the temperature increases.
Effects of Heat Energy: Heat energy produces many effects in materials and in living organisms. The effects of heat energy are the following: When heat is supplied to a body its temperature rises: When a material body, solid, liquid.
