Below are sample questions representative of the exercises included on this worksheet and related 9.67 Thermal Equilibrium skill assessments:

Problem 1Difficulty: Mastery

Which summary best matches thermal equilibrium in a closed system?

AThermal equilibrium means all objects contain the same total thermal energy and mass.

BThermal energy transfers from hotter matter to cooler matter until temperatures become more uniform while total energy is conserved within the system.

CA closed system prevents heat transfer between objects inside it.

DColdness moves from cooler matter to hotter matter until all objects become cold.

Solution & Explanation:The core idea is energy transfer from higher temperature to lower temperature within the closed system. The process reduces temperature differences while conserving energy for the whole system.

Problem 2Difficulty: Mastery

Use the data table for two samples of the same material in an insulated container. Which final-temperature prediction is best?

AThe final temperature will be closer to 85°C because that sample is hotter.

BThe final temperature will be closer to 15°C than to 85°C.

CThe final temperature will be above 85°C.

DThe final temperature will be exactly 50°C.

Solution & Explanation:Both samples are the same material, but the cooler sample has four times the mass. The final temperature is pulled closer to the larger cooler sample's starting temperature.

Problem 3Difficulty: Mastery

A metal block at 100°C is placed in water at 20°C. Later, the metal is 30°C and the water is 24°C. What is the best next prediction?

AHeat will still flow from the metal to the water because the metal is warmer.

BNo net heat flow occurs because both objects have changed temperature.

CHeat will reverse and flow from the water to the metal.

DBoth objects must instantly jump to 27°C.

Solution & Explanation:The objects are not yet at the same temperature. Since the metal is still warmer than the water, net heat transfer continues from metal to water.
