During a lab, a student stirs crushed ice into warm water. How will this system behave, according to the second law of thermodynamics?

• The ice cubes will gain heat and the warm water will lose heat until the temperature in the system is uniform throughout.

• Both the ice cubes and the warm water will gain heat. Thermal equilibrium will not be reached.

• Both the ice cubes and the warm water will lose heat. Thermal equilibrium will not be reached.

• The ice cubes will lose heat and the warm water will gain heat until the temperature in the system is uniform throughout.

Consider the scenario in which you are sitting by the campfire on a cold night. Which description best summarizes the heat transfer that occurs?

• The burning of the wood absorbs energy from its surroundings. Heat is transferred from your body to the campfire.

• The burning of the wood releases energy to its surroundings. Heat is transferred from the campfire to your body.

• The heat released by the campfire is balanced by the heat absorbed from its surroundings, so that the heat flow out of the system equals the heat flow into the system.

• Heat does not flow between the campfire and your body, as thermal equilibrium already has been achieved.
