Question

The specific heat of a certain type of cooking oil is  How much heat energy is needed to raise the temperature of  of this oil from  to 

q = ___ J

Answer 1

q = heat = mC∆T

m = mass = 2.23 kg x 1000 g/kg = 2230 g

C = specific heat = 1.75 J/gºC

∆T = change in temperature = 191 - 23 = 168ºC

q = (2230 g)( 1.75 J/g/ºC)(165ºC)q = 655,620 J = 656,000 J (to 3 significant figures)
