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 is a TRUE statement regarding this experiment?

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.
