What is the significance of area under temperature entropy TS diagram?

Temperature Entropy Diagram The area under the curve 1-2 represents the energy absorbed as heat by the system during the isothermal process. The area under the curve 3-4 is the energy rejected as heat by the system. The shaded area represents the net work done by the system.

Under what conditions is the enthalpy of a system equal to the heat supplied?

At constant pressure, the heat of reaction is equal to the enthalpy change of the system. Most chemical reactions occur at constant pressure, so enthalpy is more often used to measure heats of reaction than internal energy.

Why constant pressure lines are diverging in hs diagram?

The slope of an isobar on the h-s coordinates is equal to the absolute saturation temperature ( tsat + 273) at that pressure. The slope of the constant pressure line on an h-s curve is equal to absolute temperature and due to this reason, the constant pressure lines are of diverging nature in the superheated region.

When temperature is plotted against entropy the area under the process path is equal to?

As described on the work slide, the area under a process curve on a p-V diagram is equal to the work performed by a gas during the process. On the right of the figure we have plotted the temperature versus the entropy of the gas. This plot is called a T-s diagram.

What is the use of Mollier diagram?

The Mollier diagram is a graphic representation of the relationship between air temperature, moisture content and enthalpy, and is a basic design tool for building engineers and designers.

Why do exothermic reactions release heat?

Exothermic reactions are reactions or processes that release energy, usually in the form of heat or light. In an exothermic reaction, energy is released because the total energy of the products is less than the total energy of the reactants.

How is an isentropic constant entropy process shown on a Mollier diagram?

A vertical line in the Mollier diagram represents the isentropic process (s = C). A horizontal line in the Mollier diagram represents the isenthalpic process (h = C).
