Answer 2

what do you think @Shalante

Answer 3

If ice melts to water, do you think it is a physical or chemical change?

Answer 4

chemical

Answer 5

Its actually physical.
Water molecules in ice turns to water molecules in liquid water.

Do you think heat is gain or lost when ice turns to water?

Answer 6

Released=lost
Absorbed=gain

Answer 7

Lost

Answer 8

Ice gains heat to melt water
Just like how the sun melts ice.

Answer 9

so is it D

Answer 10

So is it D

Answer 11

So water vapor to liquid water loses heat energy.
Liquid water to ice loses heat energy

Answer 12

Read my explanation.
It says it all.

Answer 13

I think it is D am I right? @Shalante

Answer 14

When you pick a choice, explain to me why you picked it and I will tell you.

Answer 19

@AlexanderPhantomhive

Answer 20

I will tell you if it is correct if you tell me why you pick D relating it to chemistry, not just "it makes sense","it said so","you explained it"

Answer 21

I think that it is D because the diagram showed a physical change and not a chemical change

Answer 22

@Shalante

Answer 23

What about the heat?

Answer 24

it is transfered as well
