Problem
Liquid water is contained in a sealed, thin-walled glass vessel that allows heat to pass freely to the surrounding air. An electric heater immersed in the water is switched on. For the system consisting of the water and the glass vessel only, which of the following identifies the type of system and predicts the sign of the water-plus-vessel entropy change while the heater operates?
(a) Closed system; entropy remains constant.
(b) Isolated system; entropy remains constant.
(c) Closed system; entropy increases.
(d) Closed system; entropy decreases.
