Question

What are : a) Isotherms

b) Isobars

c) Isochores

Answer 1

Isotherms are lines of constant or equal temperature. They are often used on weather maps by meteorologists to give a large scale view of temperatures

Isobars are lines of constant or equal pressure on a weather map. They can be used to find areas of low or high pressure over a broad area  and they can tell us how intense the system may be

Isochore is a line or surface of constant volume on a graphic representation of a physical system.

Answer 2

Answer:

(a) Isotherms : Isotherms are the curves plotted by varying pressure against volume keeping temperature constant.

(c) Isochores : The lines showing the pressure temperature behaviour plotted at fixed volume are called isochores.
