It is like a planes wing, it causes the molecules on the top of the lid to want to "run" away from the burning steam, so they move vertically away. Some of those molecules will have some sort of slight attractive force with the lid, wether it be magnetic or so on, and if enough of them have enough attraction to the lid, then it will lift up
If the lid is tight enough to raise the pressure in the pan (as in a pressure cooker), the boiling temperature will be higher. However, if the lid just sits loosely on top, it will make the water boil sooner because not as much heat is lost and the water heats up faster.
The handle and lid of an electric kettle are made up of good insulators of heat to prevent burns or heat transfer when touching or opening the kettle during or after boiling. Using insulating materials helps keep the exterior of the kettle cool to touch while maintaining a safe temperature inside for boiling water. This design ensures user safety and convenience when handling the kettle.
Water will evaporate faster with alid on the pan, this is simple rule of kinetic energy
If there is a lid on a pot of boiling water, it can trap steam inside, leading to increased pressure and eventually causing the water to boil more vigorously. It can also result in the water boiling over the edges of the pot or the lid rattling due to the steam pressure.
Boiling water with the lid on will make it boil faster because it traps the heat and steam, increasing the temperature inside the pot.

A lid that makes it whistle when the water is boiling (so that the kettle doesn't run dry). A handle that is designed to keep cool enough to lift the kettle without potholders.
When there's a lid on the pot, the pressure of the steam builds up until the steam raises the lid a tiny amount (you may feel the lid floating on its rim since it will spin easily) and the water escapes the pot in the form of steam or water vapor. A pressure cooker is a pot with a lid firmly attached to the pot via clamps or some other means. This does prevent the water from leaving the pot. A large build up of pressure can cause the pot to explode, To prevent this a pressure cooker has escape valve(s) built in to release steam when the pressure is too high.Then water will leave the pot.

There is a heating element in the kettle. As the water boils, the inner temperature of the kettle rises. Once the boiling temperature is reached, a small thermostat is triggered which turns the kettle off, so as to not boil continually. This thermostat works optimally with the lid on the kettle fully closed, if the lid is not fully closed, it does not switch the kettle off as quickly.

A normal kettle is a semi-closed metal container (with lid and spout) of water. When placed on a flame, the water inside the kettle heats up until it reaches boiling point. It is then ready to be taken off the flame and the boiling water poured into a teapot, or some other beverage, etc.
the lid
If there is a lid on a pot of boiling water, it can trap steam inside, leading to increased pressure and eventually causing the water to boil more vigorously. It can also result in the water boiling over the edges of the pot or the lid rattling due to the steam pressure.
Boiling water with the lid on will make it boil faster because it traps the heat and steam, increasing the temperature inside the pot.
When water is boiled, it evaporates and forms steam. When the steam comes into contact with a cooler lid, it condenses back into liquid water droplets due to the drop in temperature. This is similar to how dew forms on cool surfaces in the morning.
The lid will come off because as the water heats up it expands and turns to steam. This pushes the air inside upwards so forcing the lid to rise.
