Question #939e5

Answer 1

I got E)

Explanation:

Here you need heat to change the phase of your material from solid (ice) to liquid at constant temperature.

The heat will be:

`Q=mL_f`

where:
`Q=` is the heat;
`m=` is the mass;
`L_f=` is the Latent Heat of Fusion (the heat needed to liquefy one gram of substance); for water it is: `L_f=334J/g` (from literature)

So we get:

`Q=15xx334=5010J`
