Heat and the first law of Thermodynamics

Heat transfer, and the first law of thermodynamics

This is quite a large heat-transfer rate. What happens if 5 mm of ice builds up inside the freezer, however? Now the heat must be transferred from the freezer, at -10 C, through 5 mm of ice, then through 1.5 mm of aluminum, to the outside of the aluminum at -25 C. The rate of heat transfer must be the same through the ice and the aluminum; this allows the temperature at the ice-aluminum interface to be calculated.

Why in the first law of thermodynamics is heat represented by a q

"Energy cannot be created or destroyed, but it can be transformed from one form to another."
Equation: deltaH = deltaQ + W
deltaH=enthalpy change, deltaQ=Heat content, W=work done on the surrounding.
Heat is a form of energy.
