i know that pure liquids boil at a termperature of 100 degress but what is the difference between evaporation and boiling :grumpy:

The boiling point of a substance is the temperature at which it changes from a liquid to a gas. It is specific to each substance and can be affected by factors such as atmospheric pressure.
The boiling point of a substance decreases as atmospheric pressure decreases. This means that substances will boil at lower temperatures at high altitudes due to the lower atmospheric pressure.
Evaporation is the process by which a liquid changes into a gas at a temperature below its boiling point. This occurs when the molecules at the surface of the liquid gain enough energy to escape into the air.
Evaporation can lower the boiling point of a substance because it removes some of the more energetic molecules from the liquid, making it easier for the remaining molecules to escape and reach the boiling point.
The rate of evaporation can be affected by factors such as temperature, surface area, humidity, and air flow. Higher temperatures, larger surface areas, lower humidity, and increased air flow can all lead to faster evaporation.
