b. Its particles gain energy (move faster), causing expansion and possible phase change.

Explanation: Heating increases a material's internal (thermal) energy, raising particle kinetic energy and usually increasing disorder and volume; with enough heat a phase change (melting, boiling) can occur. Options a and c/d are incorrect (heating doesn't make it more ordered or slow/lose energy).
