Question

If 125 cal of heat is applied to a 60.0 g piece of copper at 22.0 Celsius, what will the final temperature be? The specific heat of copper is 0.0920 cal/g.

Answer 1

Heat energy applied can be calculated by multiplying the mass of an object, its specific heat capacity and the change in temperature. It is expressed as:

H = mCΔT

From the equation above, we can calculate the final temperature of the system given above.

125 = 60 (0.0920 ) ( T - 22 )
T = 44.64 °C
