Question

***Need answered ASAP***... PLEASE

What happens to the temperature of the remaining liquid when some if the liquid evaporates?

A. Increases
B. decreases
C. Does not change
D. The change cannot be determine

Answer 1

d

Answer 2

Are you sure?

Answer 3

b) decreases.

Evaporation is a cooling process. Only the most energetic molecules in the liquid are able to escape via evaporation. When they do, they leave behind the other molecules that have less energy.

This means that the average energy per molecule in the remaining liquid is lower than it was before, so the temperature decreases (since temperature is a measure of the average energy per molecule.)

Answer 4

The source of heat will be able to heat the smaller volume more efficiently, thought the energy lost in boiling and evaporation may not make up for that. You must know the heat source to accurately judge.

Answer 5

The question doesn't state that it's a closed system, so the best answer is decreases. That is the point of sweating after all.

Answer 6

Are y'all in connections?

Answer 7

it would make more sense if it decrease but it would depend it could be A as well because if it evaporated then it would mean the temperature increased. Though I could be wrong, alcohol evaporates when its exposed to air so.. if that's that case C,

Answer 8

^^^ jus go with whatever he says lol hes usually always right

Answer 9

aha, they didn't say what liquid is was, soo I'd go with D then >.< <-- educated guess

Answer 10

It was b. it decreases

Answer 11

I was right :3

Answer 12

=.= depends.. on. the. liquid.

Answer 13

lol my bad then and true ^^^

Answer 14

Idk, I don't trust much school systems as I always correct my teacher and my answer are right, (i check) and its counted wrong...

Unless you specified the question wrong

Answer 15
