Below are sample questions representative of the exercises included on this worksheet and related 12.101 Temperature and Thermal Equilibrium skill assessments:

Problem 1Difficulty: Mastery

An infrared camera shows skin at 34°C near an ice cube at 0°C. Both surfaces emit thermal radiation. What is the net direction of thermal energy exchange between them?

AFrom the ice cube to the skin because ice is brighter in the image.

BNo exchange occurs because radiation requires equal temperatures.

CBoth emit energy, so net direction cannot depend on temperature.

DFrom the warmer skin to the colder ice cube.

Solution & Explanation:Both objects emit and absorb radiation, but the warmer surface emits more energy to the colder one than it receives in return. The net transfer is from higher temperature to lower temperature.

Problem 2Difficulty: Mastery

A refrigerator transfers energy from its cold interior to the warmer kitchen. Which statement best reconciles this with the usual direction of heat flow?

AThe refrigerator proves heat naturally flows from colder to warmer objects.

BThe refrigerator has no thermal interaction with the kitchen.

CWork input allows energy to be transferred from colder to warmer; spontaneous heat flow would be from warmer to colder.

DThe kitchen must be colder than the refrigerator interior whenever it runs.

Solution & Explanation:Natural heat flow is from higher temperature to lower temperature. A refrigerator uses work input to move energy in the opposite direction, so it does not violate the direction rule for spontaneous heat transfer.

Problem 3Difficulty: Mastery

The visual shows four graph panels for two objects in isolated thermal contact. Which panel represents a valid equilibrium outcome?

AThe panel where both curves end above the hotter initial temperature.

BThe panel where the two curves meet at one constant temperature between the initial temperatures.

CThe panel where both curves end below the colder initial temperature.

DThe panel where the curves end at two different constant temperatures.

Solution & Explanation:For simple isolated thermal contact, final equilibrium temperature is common to both objects and lies between their initial temperatures. Different final temperatures would not be equilibrium.
