Question

describing changes of state
how is temperature related to the physical change of a substance?

Explanation:

Temperature affects the kinetic energy of a substance's particles. Increasing temperature adds energy, weakening intermolecular forces to cause melting/vaporization (endothermic changes). Decreasing temperature removes energy, strengthening forces to cause freezing/condensation (exothermic changes). During phase transitions, temperature remains constant as energy changes bond strength instead of particle speed.

Answer:

Temperature influences the kinetic energy of a substance's particles, driving physical changes (e.g., melting, freezing) by altering intermolecular forces; phase transitions occur at constant temperatures.
