Question

How much energy is required to completely melt a 250 gram ice cube that is already at 0 degrees Celsius? Show your work & units. Expected Answer = 83,500 J

Answer 1

Q = 83500J

Step-by-step explanation:

`Q = L_(ice) *m`

`L_(ice) = 3.34*10^(5) (J)/(kg)`

`m = 250g = 0.25kg`

`Q = (3.34*10^(5) (J)/(kg))*(0.25kg)`

`Q = 83500J`
