Question

2.2.4 quiz: transfer of thermal energy
question 2 of 10
which material will feel coldest at room temperature?
a. plastic
b. glass
c. metal
d. rubber

Explanation:

The feeling of coldness at room temperature is related to thermal conductivity. Metals are good thermal conductors, meaning they transfer heat from the hand (which is warmer than room - temp materials if the hand is at body temp) quickly. Plastic, glass, and rubber are poor conductors (insulators) and don't draw heat away as fast. So metal will feel coldest as it conducts heat away from the skin more rapidly, making the skin sense a lower temperature.

Answer:

C. Metal
