STATE whether you expect the following entities to be in thermal equilibrium with their surroundings under normal circumstances.

Question

A. A desk - I think yes
B. A person- I think yes
C. The walls of a room- I think yes
D. The sun- I think no

Answer 1

I agree except for B.

People are mammals, which have internal body heat regulation. They maintain roughly the same temperature regardless of environment.

Reptiles and other cold-blooded animals cannot do this, and their internal temperature is much more greatly affected by their surroundings. They get sluggish in the cold, and are more active in warm weather.
