Question

The specific heat of a certain type of cooking oil is 1.75 J/(g⋅°C). How much heat energy is needed to raise the temperature of 2.48 kg of this oil from 23 °C to 191 °C?

Answer 1

You're given the heat capacity, a mass, and two temperatures. So, to find the energy needed to raise the temperature you would use the formula q=mcΔt.

m-mass(g)

c-specific heat capacity

Δt-change in temperature(final-initial temp)

By plugging in the given values, you would end up with:

q=(1.75 J/g°C)(2.48x1000)(191-23°)

so q=729120 J= 729 kJ
