The specific heat of copper is 0.39 j/g*degrees celcius how much heat is needed to raise the temperature of 1000.0 g of copper from 25.0 degrees celsius to 45.0 degrees celcius

In order to calculate the amount of energy needed, we will apply:

heat energy = mass x specific heat capacity x change in temperature

Q = mcΔT

Substituting the given values,

Q = 1000 x 0.39 x (45 - 25)

Q = 7,800 Joules of heat energy are needed
