Which statement is true for a cooling curve?

Question

A.
It shows how the temperature of the substance falls as heat is removed.
B.
It shows how the temperature of the substance changes when heat is applied.
C.
It shows the increase in the average kinetic energy of the particles.
D.
It shows how heat absorption affects the motion of particles.
E.
It shows how energy gain causes the temperature to fall.

Answer 1

The correct statement about a cooling curve is:

A. It shows how the temperature of the substance falls as heat is removed.

A cooling curve typically illustrates the change in temperature of a substance as it loses heat, resulting in a decrease in temperature over time.
