Question

the slanted parts of the graph represent changes in the substances (check all that apply)temperaturekinetic energystate of matterpotential energyrewatchsubmit

Explanation:

Slanted segments of a heating/cooling curve show temperature increase/decrease, which directly relates to the average kinetic energy of particles (kinetic energy ∝ temperature). Flat segments represent state changes (potential energy changes, no temp change). State of matter doesn't change in slanted parts, and potential energy is constant here.

Answer:

• temperature
• kinetic energy
