The molecules will move faster.

Heating adds energy to an object, which increases the molecules' average kinetic energy (they vibrate/translate more). Note: during a phase change (melting/boiling) added energy can go into changing bonds (latent heat) so temperature may stay constant while microscopic motion/arrangement changes.
