Question

In a sealed gas-liquid system at constant temperature, eventually...?

Answer 1

Let us study about it .

Explanation:

Evaporation

It is the process of converting liquid into vapors .

Condensation

It is the process of converting  vapors back into liquid state .

1. Suppose if we have a sealed container and we are supplying it with no or little heat , we will see that as we increase heat , the particles starts moving faster .
2. When they move they also colloide and transfer energies .
3. The kinetic energies of certain molecule increase to an extent that they leave the other particles and escape in atmosphere .
4. That is evaporation occurs .At the same time when these vapors collide with each other or with the walls of container they get cooled and again get converted to liquid state .

It is seen that  a equilibrium is reached when "rate of evaporation becomes equal to rate of condensation ".
