Show that the joule-thompson coefficient is zero for ideal gas.

Joule-Thomson coefficient for an ideal gas:

Explanation:

Joule-Thomson coefficient can be defined as change of temperature with respect to pressure at constant enthalpy.

Thus,

Also,

Also, is defined  as:

Acoording to defination, the ethalpy is constant which means

For an ideal gas,

So,

Thus, ≠0. So,

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
