Where Does Energy Go When Water Boils?

[imboring2000]

hi! I wanted to know the answer for this question: Where is the energy going when the water is boiling? We are talking about thermal energy in my class. Also, If I would place a beaker of water on a hot plate in order for it to get hot and change temperature, Would the hot plate transfer energy to the water at a steady rate?
Thanks

When the water is boiling, the energy travles from the fire to the boiler, the boiler to the water, this causes the water to "boil" which means that it is undergoing a phase change (water to gas). The energy is used for evaporation (Heat of Vaporization). Some of the energy form the water is transferred to the air.

Also, If I would place a beaker of water on a hot plate in order for it to get hot and change temperature, Would the hot plate transfer energy to the water at a steady rate? Thanks

Yeah, but the word "steady" is a little sketchy to me.

Hi there! When water is boiling, the energy is going into breaking the bonds between the water molecules, causing them to turn into vapor. This is known as the heat of vaporization and is a type of thermal energy. As for your second question, yes, the hot plate would transfer energy to the water at a steady rate. This is because the hot plate is constantly emitting heat, and the water will continue to absorb that heat until it reaches its boiling point. I hope this helps with your homework!
