Question

1. Find the saturation temperature, the changes in specific volume and entropy during
evaporation, the latent heat of vapourisation of steam at 1Mpa​

Answer 1

Answer:

The correct answer of this question is the saturation temperature at atmospheric pressure is 100°C.

Explanation:

Given - The saturation temperature, the changes in specific volume and entropy during evaporation.

To Find -  Find the saturation temperature, the changes in specific volume and entropy during evaporation, the latent heat of vapourisation of steam at 1Mpa​

Boiling water and saturated steam in the same system have the same temperature, but the steam has significantly more heat energy per unit mass. The saturation temperature at atmospheric pressure is 100°C.

The term "saturation" in thermodynamics refers to a situation where a mixture of vapour and liquid can coexist at a specific temperature and pressure. The saturation temperature is the temperature at which vaporisation (boiling) begins to happen for a specific pressure.

Answer 2

Answer:

The saturation temperature at atmospheric pressure is 100°C.

Is the correct answer of this question.

Explanation:

In the same system, boiling water and saturated steam have the same temperature, but steam has much higher heat energy per unit mass. At atmospheric pressure, the saturation temperature is 100°C.

In thermodynamics, "saturation" refers to a state in which a mixture of vapour and liquid may coexist at a certain temperature and pressure. For a given pressure, the saturation temperature is the temperature at which vaporisation (boiling) commences.

Saturated steam is defined as steam that persists at the same temperature as the water from which it is created. In other words, saturated steam exists at atmospheric pressure at around 100°C (212°F).
