The specific heat of a certain type of cooking oil is 1.75 cal/ (g c) how much heat energy is needed to raise the temperature of 2.67 kg of this oil from 23 c to 191 c

Just use the formula:

Q = cMΔT

where

Q = heat energy needed for that material to get desired temperature change (in Joules)

M = mass (in grams) so you have to convert from kilograms.

c = specific heat constant for the material being heated [in /(grams oC)]

ΔT = change in temperature (in oC)

Q = (1.75)(2.17 x 1000)(191 - 23) = (1.75)(2170)(168) = 637,980 Joules

hope that helps you in some way

also have a great day!
