For objects at thermal equilibrium, which of the following is true? a. each is at the same temperature. b. each has the same internal energy. c. each has the same heat. d. all of the above. e. none of the above.

a) Each is at same temperature

Explanation:

According to the zeroth law of thermodynamics when two objects are in thermal equilibrium with the third one then they are at thermal equilibrium with each other thus they all are at the same temperature.

Here Also objects are in thermal Equilibrium then they should be at the same temperature.

As Internal Energy is an Extensive Property that depends on the amount of gas Present thus two gases at thermal Equilibrium can have different Temperatures.        

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~
