Question

As temperature of this substance rises from 20*c to 50*c, the substance_____heat and its kinetic energy_____.

A) Absorbs; Increases
B)Releases; Increases
C)Absorbs; Remains constant
D)Remains constant;Increases

Answer 1

The answer would be:

A. Absorbs; Increases

This is why:

When a substance is heated, the molecules that makes that substance gain kinetic energy. This is because heat is energy and the substance ABSORBS it. When this happens, this causes the molecules to move faster which results in an INCREASE in kinetic energy. This would result to an increase in temperature of the substance.
