溶ける (とける) is the most general for melting (ice, snow, sugar in water). 解ける (とける) often implies something tied or frozen coming undone, and is common for ice/snow melting. 解凍する (かいとうする) is specifically for thawing frozen food or defrosting appliances.
While 溶ける can be used metaphorically (e.g., 心が溶ける 'one's heart melts'), it is not used for a person becoming less reserved. Use 打ち解ける (うちとける) instead.
