Question

An electric heater supplies 13.500 joules of heat energy to a metal block of mass 0,5 Kg. The temperature of the block rises from 20 oC to 80 oC during the heating process. Assuming that very little heat is lost from the block during the heating process, what is the specific heat capacity (c) of the metal?

Answer 1

Resposta:

c=450J/Kg°C

Explicação:

Q=m*c*ΔT

The heat energy is 13.500 joules, mass of the block is 0,5 kilogram and the temperature variation is 60°C

13500=0,5*c*60

c=450J/Kg°C

I used the mass in Kilogram but I don't know if the unity of the heat capacity is in J/g or J/Kg, I chose Kg :").
