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:
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
What is the specific heat capacity of graphite if it requires 266 J to raise the temperature of 15 grams of graphite by 25°C?
A. 1.4 J/g°C
B. 0.71 J/g°C
C. 0.43 J/g°C
D. 0.60 J/g°C
E. none of these
