What happens when a gas molecule collides with a liquid molecule at the microscopic level ?
So when the gas molecule collides with a water molecule the gas molecule may lose some momentum enough to allow it get affected by the water molecules attraction force so it become a liquid again ?dauto said:One process - evaporation - is the reverse of the other - condensation. If you understand one than you understand both. If the gas molecule loses enough energy in the collision it sticks and becomes part of the liquid.
Good, I have one more question. At the collision, as the gas molecule loses energy the liquid molecule will gain energy, can this energy be enough to make it escape from the liquid surface?? Overall, one molecule condenses while an other evaporatesdauto said:Pretty much
But an decrease in momentum means decrease in kinetic energy, right ?dauto said:Pretty much but, again, energy - not momentum - is the parameter you should be looking into.

The collision between gas molecules and liquid molecules occurs due to the random movements and collisions of the molecules. Gas molecules are constantly in motion and when they come into contact with the liquid molecules, they collide and interact with each other.
During a collision between gas molecules and liquid molecules, the gas molecules transfer energy and momentum to the liquid molecules. This can cause the liquid molecules to vibrate or move faster, leading to an increase in temperature or a change in state.
The properties of gas molecules and liquid molecules, such as their size, mass, and temperature, can affect the frequency and intensity of their collisions. For example, smaller and lighter gas molecules may collide more frequently with liquid molecules than larger and heavier gas molecules.
The collision between gas molecules and liquid molecules is a natural phenomenon and cannot be controlled. However, the conditions in which the molecules are present, such as pressure and temperature, can be manipulated to alter the frequency and intensity of their collisions.
Studying the collision between gas molecules and liquid molecules is important in understanding various processes such as gas exchange in the human body, chemical reactions, and the behavior of different substances. This knowledge can also be applied in industries such as food and beverage production, pharmaceuticals, and environmental science.
