When heated up, water molecules (and most molecules in general) will speed up, and start moving quickly. When they reach a certain heat, they turn into gas. It's quite simple.
When evaporation occurs, the temperature of the surrounding air decreases because the process of evaporation requires energy, which is taken from the surrounding environment, causing a cooling effect.
Evaporation occurs, it becomes solid inside
it becomes less dense
The phase change that occurs during evaporation is when a liquid changes into a gas. This process happens when the molecules of the liquid gain enough energy to escape into the air.
evaporation occurs
When evaporation occurs, the water molecules in the puddle transform into water vapor and rise into the air, causing the puddle to gradually decrease in size until it eventually dries up completely.
A chemical change occurs when you boil something. Also, evaporation can occur when it gets hot enough.
Evaporation is the process by which a liquid turns into gas or vapor. This occurs when the molecules in the liquid gain enough energy to escape the surface and enter the air. Evaporation happens at any temperature, but the rate increases with higher temperatures.
Both evaporation and boiling involve the transformation of a liquid into a gas. However, evaporation occurs at the surface of a liquid at any temperature, while boiling specifically happens when the liquid reaches its boiling point and bubbles form throughout the entire volume of the liquid.
Evaporation refers to the process of becoming vapor. Evaporation occurs when the sun heats up the earth surface. Evaporation also occurs when water is heated in a cooking vessel.
Boiling occurs when the vapour pressure becomes equal to the external pressure while evaporation is the escape of molecules from the surface. Bubbles appear in boiling while not in evaporation. Temperature does not effect the rate of boiling while evaporation is fast at high temperature and slow at low temperature.
The most evaporation occurs at the highest heat and lowest pressure.
