Answer:
Q =843780 J
Explanation:
Given that,
The specific heat of a certain type of cooking oil is, [tex]c=1.75\ J/g^{\circ}C[/tex]
Mass of the oil, m = 2.87 kg = 2870 g
Initial temperature, [tex]T_i=23^{\circ}C[/tex]
Final temperature, [tex]T_f=191^{\circ}C[/tex]
To find,
Heat energy needed to raise the temperature.
Solution,
The heat energy needed to raise the temperature in terms of specific heat is given by :
[tex]Q=mc(T_f-T_i)[/tex]
[tex]Q=2870\ g\times 1.75\ J/g^{\circ}C\times (191^{\circ}C-23^{\circ}C)[/tex]
[tex]Q=843780\ J[/tex]
So, the heat energy needed to raise the temperature is 843780 J.
