Given that the room temperature is greater than the temperature of the ice water, we can evaluate the statements:
A. Heat flows from the ice cubes into the water.
- False. The ice cubes are colder than the water, so heat will not flow from the ice to the water. Instead, the ice will absorb heat from the water.
B. Heat flows from the water into the ice cubes.
- True. Heat will flow from the warmer water into the colder ice cubes as they attempt to reach thermal equilibrium.
C. Heat flows from the cup into the air in the room.
- True. If the cup containing the ice water is at a lower temperature than the room, heat can flow from the cup into the warmer air of the room.
D. Heat from the air in the room flows into the cup.
- False. Since the water (and the cup) is at a lower temperature than the air, heat does flow from the water to the air, not the other way around.
E. There is no heat flow between the ice cubes and the water because they are at equilibrium.
- False. In this scenario, the ice cubes are not in thermal equilibrium with the water; heat is still transferring between them as the ice absorbs heat from the water.
True statements: B and C.
