@mos1635 @Sachintha

Answer 2

\[Q = mL\]

Answer 3

what is m and l?

Answer 4

@Sachintha

Answer 5

Ohh sorry was busy with my own question :3

Answer 6

can you help me now

Answer 7

Q - heat energy
m - mass
L - latent heat

Answer 8

so if i wanna find latent heat of fusion so do i uses Energy/mass?

Answer 9

Yeah

Answer 10

and what is the formula for latent heat of evaporation

Answer 11

It's the same. It differs by the amount of heat energy taken.

Answer 12

thanks

Answer 13

No problem! :)

Answer 14

Phase changes require extra energy to happen. A phase change is a transition from one phase of matter to another, such as from a solid to a liquid, a liquid to a gas or vice versa. If you freeze a liquid, then you are losing energy from the liquid so the heat of fusion is keeping track of this. If you boil a liquid then you are adding energy to the liquid. The heat of vaporization is how much energy you have a to add to get it "over the hump" to the next phase of matter.
