Answer : The amount of heat needed is, 1188 J
Explanation :
Formula used :
where,
q = heat needed = ?
m = mass of copper = 55 g
c = specific heat capacity of copper = 
= initial temperature = 
= final temperature = 
Now put all the given values in the above formula, we get:
Thus, the amount of heat needed is, 1188 J
