Answer to Question #177377 in General Chemistry for mel

Question

The specific heat of a certain type of cooking oil is 1.75 J/(g⋅°C). 1.75 J/(g⋅°C). How much heat energy is needed to raise the temperature of 2.27 kg of this oil from 23 °C 23 °C to 191 °C?

q= _____?______J

find q

Answer 1

$Q=cM\Delta T$

Q = (1.75)(2.17 x 1000)(191 - 23)J

Q = (1.75)(2170)(168)J

Q = 637,980 Joules
