Question

Some homes that use baseboard heating use copper tubing. Hot water runs through and heats the copper tubing, which in turn heats aluminum fins. It is actually the aluminum fins that heat the air rising through the fins.

How much energy would it take to heat a section of the copper tubing that weighs about 530.0  , from 15.97  to 26.37  ?  Copper has a specific heat of 0.3850 .

A similar issue with this question: What are the units of the given data???

If we assume them to be grams, ^oC, and kJ/g^oC,you would use the equation q = mcΔT. Plug in the values & solve. Anya, units ARE important! Get in the habit of not only listing them but using them in the calculations; they can be your guide to setting up a problem correctly.
