Question

which substance has the most thermal energy and will have the most heat flow from it?
a stovetop burner on medium (200°c)
a nuclear reactor core (1000°c)
the human body (36°c)
air at room temperature (32°c)

Explanation:

Thermal energy is related to temperature and mass. Among the given options, assuming similar masses in a comparative sense, the higher the temperature, the more thermal energy and the more heat will flow from it. The nuclear reactor core has the highest temperature.

Answer:

B. a nuclear reactor core (1000°C)
