Question

Jose has a cup of hot coffee, at 45°C. He adds some warm milk, and the resulting mixture is now 40°C. Does the mixture have more, less or the same amount of heat? Why?

Answer 1

More, because in thermodynamics, heat is energy in transfer to or from a thermodynamic system, by mechanisms other than thermodynamic work or transfer of matter.
