i think its 2 & 4

Answer 2

Answer 3

hey dood!

Answer 4

what do you think of the question?

Answer 5

Oh hai.
Um, a part of kinetic molecular theory states that temperature and kinetic energy are proportional. So, as one goes up or down, the other goes up or down.

Answer 6

ok

Answer 7

i think I'm correct then?

Answer 8

Whoa. Why are none of these correct. .-.
Heat is gained during phase changes, but the temperature stays constant.

Answer 9

cause the arrows on 2 & 4 both have them pointing up

Answer 10

oh....welll....

Answer 11

No, they're pointing in a positive direction of heat energy. Hmm...

Answer 12

oh wait, i forgot to put options ;P

Answer 13

A) 1 and 2
B) 1 and 3
C) 2 and 4
D) 3 and 4

Answer 14
