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

   The energy needed  to  raise   the  temperature   of 2.83 kg  of   the oil  from  23  to  191  is  calculated  using   Mc  delta T  formula

M= mass (  2.83  Kg  to  grams  =  2.83  x1000=  2830 grams)
C=  specific   heat   capacity  =   1.75  j/g/c
delta T=  change  in  temperature =   191-  23 =  168  c

heat   energy  =  1.75  j/g/c  x   2830  g  x  168 c=  832020  J 

I’m not sure what your trying to say here.. can you clarify again?
