Calculate the energy required to heat a beaker of water at 33 °C to boiling (Boiling is 100°C). The mass of the water is 54.1 g and it has a specific heat of 4.18 J/g*°C.

Question

Calculate the energy required to heat a beaker of water at 33 C to boiling

Answer 1

q = heat energy = mC∆T

m = mass = 54.1 g

C = specific heat = 4.18 J/g/degree

∆T = change in temperature =100º - 33º = 67º

q = (54.1 g)(4.18 J/g/degree)(67 degrees)

q = 15,151 J = 15.2 kJ
