The temperature of water stays the same because it has reached an equilibrium. Once it reaches a certain point it changes phases to gas. The water left boiling stays has to stay the same temperature otherwise it would all be gas.
Temperature stays constant because there's no change in average kinetic energy.
Molecules gain kinetic energy, but at the same time some of them escapes from the liquid, so the average kinetic energy stays the same.

∙ 15y agoThe boiling point of pure water is 100 degrees Celsius this is to due with the forces holding the H2O molecules together. When water is solid (frozen) there are lots of bonds holding the different H2O molecules together. However these require little energy to be broken therefore water has a low melting point. When water is liquid a lot of the inter molecular forces are broken yet some are still joined, the energy at the point where water boils it the equivalent to 100 degrees Celsius. As pure water is made up of identical H2O molecules the energy required to break the bonds will always be the same- this the boiling point remains constant. However when you get impurities, that is when the boiling point will change.

∙ 13y agoThe boiling water stays the same temperature until the intermolecular bonds between water molecules are all broken. Then the temperature of the vapour can be heated. This is the latent heat of vaporization.

∙ 12y agobecause when something changes phase from solid to liquid, or from liquid to gas, it takes energy to break the intermolecular interactions. These interactions between the water molecules are what make it solid. When you have ice, these interactions are strongest, which is why ice is hard. Then when you have water, the interactions are not as strong, and although the water still "stays together" it is now a liquid and moves and flows freely. Then when all the interactions are broken, it become a gas, or steam, and now none of the water molecules are attached to any other molecules

∙ 9y agoThe energy is being used to power a phase change, and none is left to raise the temp.
OR (if you like)
The energy is being used to increase the linear velocity of the molecules rather than their vibrational energy (which we measure as temperature.

∙ 15y agoBecause any water with a temperature higher than that becomes a gas and escapes, leaving only those particles at that temperature.

∙ 14y agobecause the water that gets hotter turns into steam

∙ 12y agosince water has a high heat capacity, it can hold a lot of heat before ever actually changing it's temperature. once it reaches a certain point after boiling, it will then start to evaporate.

What effect does adding salt have on the melting point of ice?
Salt alters the melting point and boiling point of water by altering the molecular structures with the sodium and chloride contents of the salt. When added to water, it will boil before it hits 212 degrees. When added to ice it also reduces the temperature that water freezes at, making the water stay liquid longer at temps lower than 32 degrees.
Why is water a better fluid for use in a hot pack than ethyl alcohol?
Water has a higher boiling point than ethanol, and so will evaporate more slowly at high temperatures than ethanol. Also, I think water has a higher heat capacity, which means it will stay hot longer.
What happens when heat is added to boiling water?
Depending on how much heat you add, more and more water will evaporate. It should be noted that the temperature will notincrease, however. The temperature of the water will stay the same until all the water has changed state and become steam, or water vapor, if you prefer.
Explain why molality is used for boiling point elevation and feezing point depression calculations and molarity is used for osmotic pressure calculations?
Molality is independent of temperature, so when you are trying to find changes in boiling and freezing points you need something that will stay constant regardless of the change in temperature. Molarity is temperature dependent and also is based on the volume of a solution, both of which are needed to calculate pressure using the ideal gas law, PV=nRT. Osmotic pressure is similar but we substitute the number of moles of the solution and the volume by using the molarity, you cannot do this with molality, since it is dependent on mass, not volume.
What is the melting and boiling point of flour?
Flour does not melt. It is an organic material that will char and burn as the temperature increases. The flour is mainly carbohydrate that will burn to produce carbon dioxide and water but due to the high carbon content it could just slowly turn into charcoal if there is no air constantly mixed in.
How is the boiling of liquid related to the evaporation process?
Evaporation is partial boiling. When a liquid reaches its boiling point, no molecules of water will stay liquid and evaporation is at 100%.
What is wrong in choosing the melting point and the boiling point of water as standard fixed point?
The melting and boiling points of water change as the air pressure changes. For example, there is a certain air pressure in which steam, water and ice will stay like that forever.
How can water in an engine stay a liquid when the temperature is above its normal boiling point?
The cooling system is pressurized and requires a higher temperature to reach boiling.
Why does water stay at the same temp after it starts to boil?
It takes a certain energy to convert water to steam. Any additional energy you supply to the water, as heat, will be taken away by water converting to steam. The maximum temperature of a liquid is its boiling point so water shows constant maximum temperature 100o Celsius (if it is pure).
What happens if a glowstick was in boiling water?
It stay the same
If you continued t heat a pot of water after it reached it boiling point what would happen?
Eventually the boiling water would be completely evaporated, leaving a dry pot. An aluminium pot would have the bottom burnt out.
Can boiling water will stay at the same temperature when you lower the heat under it but keep it boiling?
Yes
Does the boiling point of a liquid decreases increases or stay the same if the intermolecular force increases?
Generally, the boiling point of a liquid increases if the intermolecular force, i.e. pressure, increases.
Why is boiling water a physical change?
Physical change because the water molecules stay unchanged during boiling, also the germination phase helps this be proved correct=)
When the sea in Chile evapourated why didn't the salt disappear with water?
salt has a much higher boiling point than water. Water will start evaporating, depending on the temperature, and the local saturation of the surrounding air (the humidity). Dissolved seasalt (NaCL -> Na+ + Cl- ) will stay behind, and eventually return to its salt-state. since its melting point is 801 °C (1,474 °F) and its boiling point 1,465 °C (2,669 °F), it will not evaporate.
