Question

How much heat is required to lower the temperature of 1000 g of copper from 100°C to

25°C if the specific heat capacity of copper is 0.385 J/g°C?
32,875 J
-28,875 J
28,800 J
-28,875 g

Answer 1

Heat = -28,875 J

Step-by-step explanation:

We can solve for heat using this equation.

(heat) = (mass)•(specific heat)•(change in temperature)

Plug in what you know

(heat) = 1000g•(0.385J/g°C)•(25°C-100°C)

Solve

Heat = -28,875 J
