Question

Explain why steam at 100 degree Celsius is better for heating purpose than boiling water at 100 degree Celsius

Answer 1

Steam has more energy than boiling water. It possesses the additional latent heat of vaporization. Therefore, steam at 100 C is better for heating purposes than boiling water.

Answer 2

Answer:

At a pressure of 1 atm, water boils at a temperature of 100 degrees Celsius. The temperature of the liquid, the pressure of the atmosphere, and the pressure of the vapor all affect its boiling point.

Explanation:

Steam at 100 °C has more heat than water at the same temperature. Water gets converted into steam on gaining heat. Due to this latent heat of vaporization, steam at 100°C is better for heating than boiling water at 100°C.

While the boiling point increases with pressure, the heat of vaporization decreases. At a certain point, known as the critical point, it fully disappears. It is known as the latent heat of vaporization.

Hence, steam at 100 degrees Celsius is better for heating purposes than boiling water at 100 degrees Celsius because of the latent heat of vaporization.
