When boiling water is thrown into cold air, it quickly evaporates and turns into water vapor. This happens because the cold air causes the hot water to cool rapidly, leading to a phase change from liquid to gas.
When antifreeze is added to water, it lowers the freezing point and raises the boiling point of the mixture. This helps prevent the water from freezing in cold temperatures and boiling in hot temperatures, making it more suitable for use as engine coolant.

It will always run cold so it will run inefficiently.
The motivation is to avoid uncontrolled boiling and splashing.
Boiling takes place and it leads to the movement of hot water upwards and the movement of cold water downwards.
I recommend putting hot water in your kettle and timing it getting to the boil, and repeating with the same volume of cold water. Then have a think about why this happens.

After boiling, the film on water evaporates and disappears.
When a cold spoon is placed near the vapor of boiling water, the water vapor cools down and condenses into water droplets on the surface of the spoon. This happens because the cold temperature of the spoon causes the water vapor to lose energy and transform back into liquid form.
Boiling water turns to vapor in the cold because the temperature difference between the hot water and the cold air causes the water to evaporate and turn into vapor.
A steam engine is a heat engine. A steam engine uses boiling water to produce mechanical work. It uses the steam from the boiling water as its working fluid.
