The heat absorbed is
Explanation:
The heat absorbed is
The mass is
The specific heat of copper is
The change in temperature is
Therefore,

Here are all informations that we have :
- Mass of copper(m)
#=5.82g# - Specific Heat Capacity (I will just name it SHC) of copper
#=0.385 J(g°C)^-1# #rarr# simpler way to write 0.385 J/g°C - Change in temperature (
#DeltaC# )#=328.3°C-21.5°C=306.8°C#
Then we start
Firstly the formula,
SHC
Then we replace the values and calculate it
Therefore, heat absorbed
(I put the answer at 3 significant figures (s.f) but for further calculations use the first value obtained)
