The question I'm trying to figure out is:
"An electric range burner weighing 624.0 grams is turned off after reaching a temperature of 460.1°C, and is allowed to cool down to 22.4°C."
And there is more that I have to figure out, but I need to use the information given above to find the change in energy to solve the rest of the problem. Please help!
If I have a mass, a starting temperature, and an ending temperature, how do I calculate the change in energy (delta E)?

The missing information is the specific heat of the material of the burner.
That is essential.
so the energy change is the mass * specific heat * change in temperature.

Not enough info.
Always provide the complete problem, partials are never adequite.
