Question

State Charle's law and derive Charle's gas equation. State the nature of volume - temperature curve at constant pressure​

Answer 1

Explanation:

Charles' law states for a fixed amount of an ideal gas its volume is directly proportional to its temperature at constant pressure.

Equation

The equation of the law is PV = k. Here, k is a constant.

The equation of charles' law

V=k×T

At a fixed pressure, when the volume is varied, the volume-temperature relationship traces a straight line on the graph and on moving towards zero volume all lines intersect at a point on the temperature axis which is -273.15˚C. Each line in the graph of volume Vs temperature is known as isobar (Since pressure is constant). The least hypothetical temperature of -273˚C at which a gas will have zero volume is called as absolute zero.
