FREE Expert Solution

We’re being asked to determine the specific heat capacity (C) given that 15 g of graphite was raised by 25 ˚C


The amount of heat Q is given by:


Q = mcT


where m = mass (in grams), c = specific heat, ΔT = change in temperature = final T – initial T. We’re given the following values:

m = 15 g

c = ???

ΔT = 25 ˚C = 25˚C
