How does he amount of energy change during boiling?
During boiling the temperatre of the boiling liquid does not go up. The energy input into the boiling liquid is taken away as the latent heat of evaporation by the escaping gaseous phase.
Where does energy go when it seems to disapear?
When energy "disappears" it has actually turned into heat. All reactions have heat as a waste product.
Where does motion energy go?
"go" isn't really the right word, it transforms (like all energy) mostly into the form of heat energy.
Where does energy go when it is transferred?
It is lost as heat.
Can energy go through water?
Absolutely! Electric energy, kinetic energy, sound waves, light waves, heat ... all kinds of energy travel very well through water.

Where does heat energy go when temperature is not rising?
During boiling all the heat supplied to the liquid is used up in overcoming the intermolecular forces present among the molecules of the liquid. That is why the temperature of the liquid does not change.
Is boiling an egg endothermic or exothermic?
It is endothermic as the water mus gain energy to go from a liquid to a gas.
Where does the heat go during boiling time?
at boiling point heat used for changing the state of matter

Why steam causes more severe burns than boiling water. give reason.?
So, steam must lose its heat of vaporization. Think about how it would lose it. Where would all that energy go? It condenses by inputting all the potential energy it has by being a gas into the skin of the person who touches it. Therefore even though steam only has slightly more kinetic energy than almost boiling water, it has a lot more total energy.
How does water go from room temperature to boiling?
Add heat.
Does heating always increase temperature?
No. For example when you heat boiling water, its temperature remains the same. the thermal energy will go to breaking the attraction between the atoms
What transformation does grass go through in a food chain?
It goes from light energy from the sun to chemical energy to chemical, mechanical, and heat energy and the chemical energy can go to mechanical and heat energy. Then the remaining chemical energy goes to chemical, heat, and mechanical energy again and it keeps on repeating.
Where does energy go when it is transferred?
It is lost as heat.
Why temperature remains constant during the process of melting or boiling?
This is because of latent heat. When a substance is being melted, heat is supplied to the solid until its melting point is reached. When the solid reaches that temperature, any additional heat energy is used - not to raise its temperature - but to cause the phase to change from solid to liquid. The amount of energy required (per unit mass) is the latent heat of melting (or freezing, when the process is reversed) for that substance. When the phase change is complete, any further heat energy supplied will, once again, go towards raising the temperature.The same thing happens at the boiling point except that this time it is the latent heat of evaporation/condensation.
