Tia learns that the temperature of rock in Earth's mantle varies depending on its location. Rock located close to the lithosphere is about 1,000 °C, and rock located close to the outer core is about 3,700 °C.
Tia uses the formula shown below to calculate the amount of heat that needs to be added to a 5-9 piece of rock
in order to raise its temperature from 1,000 °C to 3,700 °C. She uses 0.79 J/g °C for the specific heat of the rock.
q=MCAT
q= amount of heat
m= mass
C = specific heat
AT=change in temperature
What is the amount of heat, in joules, that needs to be added to the piece of rock.
