Liquid and gas are caused by the kinetic energy of the particles within a substance. In a liquid, the particles have enough energy to move past each other but are still held together by intermolecular forces. In a gas, the particles have even more energy and move freely, with very weak intermolecular forces.
To change a gas to a liquid, you need to lower the temperature of the gas below its boiling point while keeping the pressure constant. This process is known as condensation and it causes the gas particles to slow down and come together to form a liquid.
When a liquid is heated, its temperature increases and eventually reaches its boiling point where it turns into a gas. The heat energy causes the molecules in the liquid to move faster and further apart, leading to the change in state from liquid to gas.
Bubbles are formed due to a combination of surface tension and gas trapped in a liquid. The surface tension of the liquid causes the bubble to retain its spherical shape. When a gas is introduced into the liquid, the surface tension pulls the liquid molecules together around the gas to form the bubble.
Condensation is the process by which a gas changes into a liquid state due to a decrease in temperature or an increase in pressure. This transition causes the gas particles to come closer together and form a liquid phase. It is the opposite of evaporation.

thats evaporation and heat causes it
An increase in pressure typically causes more gas to dissolve in a liquid. This is because higher pressure forces more gas molecules into the liquid phase, increasing the solubility of the gas. Additionally, lower temperature can also increase gas solubility in a liquid.

A liquid is transformed in a gas.
When a gas is heated, it gains energy and its particles move faster. To condense a gas into a liquid, the gas needs to lose energy, typically by being cooled down. This causes the gas particles to slow down and come closer together, forming a liquid.
Gas turns to liquid when energy is lost. The density of a gas is much less that the density of a liquid. Thus, when energy is lost and the particles of the gas are able to condense, it becomes a liquid.
The process by which radiant energy from the sun causes a liquid to change into a gas is called evaporation. When sunlight shines on a liquid, it provides the energy needed to break the bonds holding the liquid molecules together, allowing them to escape into the air as gas.
When heat is added to a liquid, it causes the molecules in the liquid to gain energy and move faster. This increased movement causes the liquid to change into a gas through a process called evaporation or boiling.
