## Homework Statement

Define specific heat capacity and latent heat of fusion.

Copper melts at a temperature of 1356 K with a latent heat of fusion

of 210,000 J/kg (Joules per kilogram). Calculate the thermal energy required

to convert a copper bar with a mass of 40 kg at a temperature of 280 K into

molten metal at 1360 K if the average specific heat capacity of copper (liquid

and solid) is 385 J/kg/K (Joules per kilogram per Kelvin) in the temperature

range considered here

## Homework Equations

energy SCH(specific heat capacity) * mass * change in temp

## The Attempt at a Solution

i tried to use this formula but the numbers am gettin isnt write , if possible can someone guide me on how to do this or what am i doing wrong, am good with biology but am am also learning physics which is very difficult for me .
