Answer: An amount of 
heat is required to raise the temperature of 4.64kg of lead from 150°C to 219°C.
Explanation:
Given: mass of lead = 4.64 kg
Convert kg into grams as follows.
The standard value of specific heat of lead is 
.
Formula used to calculate heat is as follows.
where,
q = heat energy
m = mass of substance
C = specific heat of substance
= change in temperature
Substitute the value into above formula as follows.
Thus, we can conclude that heat is required to raise the temperature of 4.64kg of lead from 150°C to 219°C.
Yes it is burned and I need to do that question as well for my class
