Question

what is the effect of adding heat to a solid substance?
a the substance contracts
b the particles stop moving
c the particles vibrate more
d the particles become more rigid
e the substance loses energy

Explanation:

Adding heat to a solid increases its thermal energy. In a solid, particles are in fixed positions but vibrate. With more heat, the particles gain kinetic energy and vibrate more vigorously. Solids generally expand with heat (not contract), particles don't stop moving as heat is added, they don't become more rigid, and adding heat means gaining energy not losing it.

Answer:

C. The particles vibrate more
