Answer to Question #191872 in Physics for John

Question

a) Determine the heat required to raise the temperature of 375g of olive oil from

103^oCto 145^oC

The specific heat capacity of olive oil is 1970Jkg^-1K^-1.

Give your answer to the appropriate number of significant figures.

Answer 1

$$Q=mc\Delta T,$$ $$Q=0.375\ kg\cdot1970\ Jkg^{-1}\ \!^{\circ} C^{-1}\cdot42^{\circ}C=3.1\cdot10^4\ J.$$
