Yesterday… We began our investigation of conductors and insulators and expansion and contraction To review expansion and contraction we will watch a short video that sums this up
Expansion For any single state of matter, when temperature rises, atoms or molecules move further apart. Most substances or mixtures of substances expand when heated.
Contraction When heat is taken away in a solid, liquid, or gas it will normally decrease in volume. The opposite of expansion.
