The Specific Heat Of A Certain Type Of Cooking Oil Is 1.75 Cal/(G·°C)

We’re being asked todetermine the amount of heat (Q)needed to raise the temperature of2.02 kg cooking oilfrom23 ˚C to 191 ˚C. Theamount of heat Qis given by:

wherem = mass (in grams), c = specific heat, ΔT = change in temperature = final T – initial T. We’re given the following values:

m = 2.02 kg

c = 1.75 J/g • ˚C

ΔT = 191 ˚C – 23 ˚C = 168 ˚C

The specific heat of a certain type of cooking oil is 1.75 J/(g • °C). How much heat energy is needed to raise the temperature of 2.02 kg of this oil from 23 °C to 191 °C?
