Complete question:
The specific heat of a certain type of cooking oil is 1.75J/g°C. How much heat energy is needed to raise the temperature of 2.63 kg of this oil from 23 °C to 191 °C?
Answer:
The heat energy required to raise the temperature of this cooking oil is 773220 J
Explanation:
Given;
mass of the cooking oil, m = 2.63 kg = 2630 g
specific heat capacity of the cooking oil, C = 1.75J/g°C
initial temperature of the cooking oil, T₁ = 23° C
final temperature of the cooking oil, T₂ = 191° C
The heat energy required to raise the temperature of this cooking oil;
Q = mcΔT
Q = 2630 x 1.75 x (191 - 23)
Q = 773220 J
Therefore, the heat energy required to raise the temperature of this cooking oil is 773220 J
