Question

It takes 150 J of energy to heat 10 g of substance 1 from 25oC to 50oC. It takes 250 J of energy to heat 10 g of substance 2 from 25oC to 50oC. Which substance has a higher specific heat capacity?

Answer 1

Substance 1: c=Q/(m*ΔT)=150/(10*25)=0.6 J/g^oC

Substance 2: c=Q/(m*ΔT)=250/(10*25)=1 J/g^oC

Answer: Substance 2 has a higher specific heat capacity
