Experiment Analysis: Water Containers: Thermal Discussion

APPH12-EKB2EZ

A group of physics students pours some hot water into Container 1 and some cold water into Container 2. For the duration of a 40-minute class period the students record temperature of each container. The results are shown in the graph above.

Which of the following statements is consistent with this information?

A

Container 1 had a greater volume of water than Container 2.

B

The material of Container 1 has a smaller thermal conductivity than Container 2.

C

Containers 1 and 2 and the water within them are all approaching thermal equilibrium with the surroundings.

D

Over the course of the class period, Container 2 absorbed as much heat as Container 1 emitted.
