The molecules in which of the following have the greatest average molecular kinetic energy?
A)air in a person's lungs
B)ice cubes in a glass of iced tea
C)raindrops collecting in a puddle
D)water boiling in a pot on a stove

Question

Quizplus · Accepted Answer

The average molecular kinetic energy of a substance is directly related to its temperature. Water boiling in a pot on a stove is at a higher temperature than the air in a person's lungs, ice cubes in a glass of iced tea, or raindrops collecting in a puddle. Therefore, the molecules in boiling water have the greatest average molecular kinetic energy.
