-- As more water evaporated from lakes, rivers, ponds, and people, the water vapor in the atmosphere would build up and build up and build up, until the atmosphere could not hold any more water vapor.
-- The water would stay there in the atmosphere. There would never be any more rain, sleet, hail, fog, drizzle, mist, or snow.
-- Rivers flow out of lakes and ponds, carrying lake water to the sea. Rain keeps the lakes refilled. The lakes would eventually dry out as the rivers drained them, and then the rivers would run dry. It would be the end of trees, forests, and farming.
-- At the instant when the atmosphere became full of all the water vapor it could hold, all evaporation on Earth would stop.
. . . . . When you washed the dishes, you could leave them standing in the drainer rack for a week, but they would never dry.
. . . . . You could hang up your bath towel and the laundry in your room or in the back yard, but it would never dry.
. . . . . When you boiled a pot of water on the stove, I'm not sure exactly what would happen, but I know that the steam could not just rise from the pot and disappear. The atmosphere couldn't absorb it, so I guess it would be this dense cloud of boiling hot fog that would rise from the pot and fill the kitchen. If you walked through it, it would swirl and drift around. Eventually it would settle on the walls, and when the droplets got big enough, they would run down the walls and make puddles on the floor.
. . . . . It would be pretty bad for people and animals. We generate a lot of heat inside our bodies, and we get rid of the heat by perspiring. Moisture comes out of our skin and evaporates into the air, which takes heat with it. If the atmosphere was full with as much water vapor as it could hold, then perspiration could not evaporate. We would ALWAYS be walking around in 100% humidity, with water running off of our skin onto the floor. The only way we could cool ourselves would be to pour cold water on ourselves. Anybody who didn't do that every couple of minutes would pass out from heat exhaustion, as his inside temperature got too high.
Our dogs don't even perspire. The only way they can get rid of heat is to make their tongues wet and then blow air over it. That's why when they run, or when the weather is hot, they drink a lot and pant fast. The water evaporating from their tongues is the only way they can get rid of heat. If the atmosphere could not take any evaporation, then our dogs would probably stop moving around at all, and just lay around all day, drinking cold water.
In short, I think it's accurate to say that if condensation of water in the atmosphere stopped, then evaporation would stop, and it would only be a matter of time before life on Earth stopped.
It will happen to cause that the water will be returned back and it will not be evaporated, etc, look into the carbon cycle or water cycle for your answer
the human body isn't very efficient at converting food into useful work. The human body is less than 5% efficient most of the time. The rest of the energy is converted to heat, which may or may not be useful, depending on how cool or warm a person wants to be.
