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 2.16 kg of this oil from 23 °c to 191 °c?

Respuesta :

Ok so we know:
The specific heat capacity 1.75
The mass of substance 2160grams
Change in temperature 168°C

So the heat energy 'q' required is:

q = mCT
= 2160x1.75x168
=635040 Joules, or 635.04kJ

Hope this helped
