1) Conduction.

Heat transfers to a spoon as the heat energy is passed from the coffee to the spoon through conduction.

2) Radiation

The heat on the glass surface gets radiated into the chair which causes the chair to warm up.

3) Convection

The globs are hot and less dense, which rises to the top whereas the cold globs are more dense which causes it to settle down.
