Question
Explain why, steam at $100^\circ C$ is better for heating purposes than boiling water at$ 100^\circ C.$
✓

Answer

It is because of the fact that steam at $100^\circ C$ contains more heat, in the form of latent heat, than boiling water at $100^\circ C.$ Hence, steam would give out $22.5 \times 105$ joules per kilogram more heat than boiling water.
