Microwaves cause water molecules to vibrate. Heat is basically the amount that a molecule/atom is vibrating. (That's why a hot gas expands, or why an aerosol can gets cold when you use it for too long, it needs heat for the molecules to expand into a gas) So, the microwaves causing the molecules to vibrate IS the heat. No friction is involved.
