Question 7 • *25-26 KCS18 Chemistry IC

Why does a glass containing an iced beverage feel cold?

Answer
A
Molecules in the glass are moving faster than molecules in the skin.
B
Molecules in the skin are moving faster than molecules in the glass.

Explanation

The skin is warmer than the glass, so its molecules have greater average kinetic energy and move faster. Thermal energy flows from the warmer skin to the colder glass, making the glass feel cold. Choice A reverses which molecules are moving faster.
