The heat is gained by Cu when 51. 8 g of Cu is warmed from 15. 5°c to 76. 4°c If the specific heat of Cu is 0. 385 j/(g · °c) is 999.42 J.
Specific heat is defined as the heat which is required to raise the temperature by 1°C of the unit mass of a given substance by a given amount.
We are required to calculate the quantity of heat energy gained by Cu
As we know that,
Q = m × c ×∆T
where,
Q is the quantity of heat energy
m is mass of substance = 0.051kg
c is specific heat of substance = 385J/kg.°C
∆T is change in temperature = 50.9
By substituting all these value we will get,
Q = 0.051 × 385 × 50.9
Q = 999.42J
Thus, we calculated that the quantity of heat gained by 0.051kg of Cu is 999.42J.
