Question

How much heat energy is required to raise the temperature of 0.367 kg of copper from 23.0 C to 60.0 C ? The specific heat of copper is 0.0920 cal/(g x C)
If 125 cal of heat is applied to a 60.0 g - piece of copper at 23.0 C, what will the final temperature be? The specific heat of copper is 0.0920 cal /(g x C)

Answer 1

Note: We must keep the units we use consistent. The Cp is given in cal/gC so we will use cal for energy, grams for mass and C for temperature.
1)
Heat supplied can be calculated using:
Q = mCpΔT; where m is the mass, Cp is the specific heat capacity and ΔT is the temperature change.
Q = 367 x 0.092 x (60 - 23)
Q = 125 Cal

2)
Using the same equation:
125 = 60 x 0.092 x (T - 23)
T = 45.6 C
