Molecules collide with the glass, and the glass molecules then transmit that energy to the outside.

Answer 1

Molecules collide with the glass, and the glass molecules then transmit that energy to the outside.

(Heat is conducted from the reacting mixture into the glass, then lost to the surrounding air by conduction and convection.)
