a 3 Raza was heating water in a vessel that was closed with a lid. After some time, he observed that the water started to spill out of the vessel through the sides of the lid. Why do you think this happened?

Answer:
Well, boiling water from a pot produce vapour at about 100°C, about since it depends from the pressure and the distance (temperature drop) above the water surface.
This vapour will make contact with the lid of the pot, the lid will be at a temperature well bellow the 100°C, because its upper surface is in contact with the surrounding air (let's say 30°C) but hotter than that, since heat is transferred from the pot to the lid through metal heat conduction and from the vapours reaching the lid; we may assume that the lid will reach a temperature of let's say 60°
