Why does an evaporating liquid cool down, according to the kinetic molecular theory? a. heat is required to evaporate a liquid. b. heat is lost through elastic collisions. c. the highest velocity molecules are lost. d. heat must be dissipated to break the liquid bonds.

The highest velocity molecules are lost.

Explanation:

When liquid gets energy, its molecule kinetic energy increases. So molecules move so fastly, as result few highest velocity molecules breaks the forces and evaporates. Due to this removal, overall energy of the system become less which causes the liquid to be cool.

the answer is a. co2, this would be colder than the : )

explanation:

girl imma just put my comment here because i need a couple point okurrttt
