What amount of heat is required to raise the temperature of a substance?

Liquid methanol has a heat capacity of 81.6 J/(K mol). How much heat is required to raise the temperature of 20.0 g of liquid methanol from 25 C to 40.0 C?

Solution Preview

Remember what your units are: J/(K mol).

81.6 J are required to raise the temperature of one mole of methanol by one degree. Therefore if you have ...

Solution Summary

Remembering our units J/K mol we determine how many moles are in 20g of methanol. How much heat required can be determined by: specific heat x # degrees x # moles. Full solution. 125 words.
