Question

How can you describe the specific heat of a substance if it takes approximately 420 J of heat to raise the temperature of 7 g of olive oil by 10 °C?

Answer 1

Solution.

$m=7g=0.007kg;$

$\Delta t=10^oC;$

$Q=420J;$

The specific heat of a substance is the amount of heat that must be provided to a substance weighing 1 kg to heat it by 1^oC.

$c=\dfrac{Q}{m\Delta t};$

$c=\dfrac{420J}{0.007kg\sdot10^oC}=6000\dfrac{J}{kg^oC};$

Answer: $c=6000\dfrac{J}{kg^oC};$
