Question

A sample of nickel weighing 425 grams was initially at atemperature of 26.20 C. It required 975 Joules of heat energy toincrease the temperature to 31.55 C. What is the specific heat ofthe nickel? please show formula,what each number means,and how tosolve thanks A sample of nickel weighing 425 grams was initially at atemperature of 26.20 C.

Explanation / Answer

We Know that Q = mC dt Where Q = amount of heat required = 975 J            m = mass of Ni = 425 g            dt = change in temperature = 31.55 - 26.2 = 5.35 oC             C = specific heat of the nickel = ? Plug the values we have C = Q / mdt                                         = 0.4288 J / g oC
