makes the molecules move faster. dding heat to water gives the molecules more kinetic energy, resulting in faster motion. It does not change the energy level of electrons or the number of electrons in the molecules.
If heat is not cut off after water starts boiling, the following will happen.
1) more energy is absorbed by the water; the excess energy leaves the system via the escaping steam; the water level drops until no more water left
2) when the water container becomes dry, the pot starts becoming red hot. The excess heat will be ferried away through convection and radiation. An aluminum pot may burn, burst into flame. The surrounding air will turn very hot. If paper products are in close proximity, they will catch on fire (Aluminum foils will too). Nothing good will happen thereafter.
=================================================
The boiling point of water at standard temperature is 100 oC.
100 degree celcious only
Yes.
increase kinetic energy.
If the energy is heat, the water will warm up. If it is kinetic, like throwing it against the wall, the glass will absorb the energy and probably smash into bits.
Latent heat is the amount of energy that is needed to change the state of matter. Either from a solid to a liquid, from a liquid to gas or vice versa. For example if you boil a kettle of water, energy or latent heat is added to the water from the element within the kettle. The water will heat up and eventually turn to steam.
Both the stirring and the heat energy added will increase the internal energy, so all you need to do is add both together. Don't forget to convert the calories to joules first.
it produces a change:: example::: say if u put cold water in a pot, and added heat from the stove so the pot of water as u can see the heat from the stove will make the water to vapor and if u see bubbles rising from the pot that is the gas escaping... so that is ow it changes from one state to another if heat iz added so water it will evaporate and if heat iz not added to the water it would turn into ice
increase kinetic energy.
Energy in the form of heat must be added to the water.
Heat energy is transferred from the hot water to the cold.

Molecules move faster when heat energy is added to to water. The water temperature mayincrease or some or the molecules may get enough energy to change phase from solid to liquidor from liquid to vapor.
yes heat is added
No. Steam is warm water vapor. Heat is added or external energy that causes a rise in temperature.
When water is heated, energy is being added to it, this causes it to change form a liquid to a gas
Thermal to kinetic when it boils
No, thermal energy is entirely energy added for heat.
If the energy is heat, the water will warm up. If it is kinetic, like throwing it against the wall, the glass will absorb the energy and probably smash into bits.
added to a reaction in the form of heat.
