Question

What is the specific heat capacity (in J/g°C) of copper if 100 grams of the metal absorbs 1500 J of heat and its temperature increases by 20°C?

Answer 1

To calculate the specific heat capacity of copper, we can use the formula:q = mcTwhere q is the heat absorbed  in joules , m is the mass of the substance  in grams , c is the specific heat capacity  in J/gC , and T is the change in temperature  in C .We are given the following information:q = 1500 Jm = 100 gT = 20CWe need to solve for c:1500 J =  100 g  c  20C Now, we can solve for c:c = 1500 J /  100 g  20C c = 1500 J / 2000 gCc = 0.75 J/gCThe specific heat capacity of copper is 0.75 J/gC.
