Aluminum has a specific heat of 0.897 J/gºC. A piece of aluminum absorbs 5000 Joules of energy and undergoes a temperature change from 100 ºC to 200ºC. What is the mass of the aluminum?

Answer 1

q = mass x specific heat x change in temperature

q = m x c x ΔT

Use the equation above to solve for mass

m = q / c x ΔT = 5000J/ (0.897 J/gºC) x (200-100) ºC= 55.7 g
