Question

Matter can be converted from one state to the other by _____ or _______ of heat energy.

• A. absorption
• B. evolution

Answer 1

(1) Heat causes an increase in the energy of rapidly moving particles.

(2) This increase in energy forces the molecules to move further apart causing an increase in volume and leading to expansion.

Therefore, matter can be converted from one state to the other by absorption or evolution of heat energy.
