Answer: The heat that is given off is -570J.

Step-by-step explanation:

Step 1: Write the given and the required in the problem.

mass = 50g

specific heat capacity of copper = 0.38J/g°C

Initial Temperature = 80°C

Final Temperature = 50°C

Step 2: This is an example of a Calorimetry problem. The equation to solve this problem is q = msΔT where

q = heat

s = specific heat capacity

ΔT = change in temperature

Step 3: Substitute all the values given and solve for the value of heat.

q = msΔT

q = 50g(0.38J/g°C)(50°C - 80°C)

q = -570J

The heat that is given off is -570J.
