When water is boiled, the heat energy is transferred to the molecules of water, which begin to move more quickly. Eventually, the molecules have too much energy to stay connected as a liquid. When this occurs, they form gaseous molecules of water vapor, which float to the surface as bubbles and travel into the air.

How does warm water make more bubbles than cold and hot water?

My answer is, that there are air bubbles in the bottom of it, (WHEN ITS BOILING) Than those air bubbles rise to the top, & That's how hot water bubbles more than cold water.


Bubbles in the water?

The bubbles you see in water are air bubbles. they rise to the top then pop when they reach the surface.


Can a liquid dissolve a gas?

Gases do dissolve in a liquid, an example being air dissolved in water. When water is boiling, the bubbles that rise to the top are the dissolved air separating from the water.


What is in the bubbles of boiling water?

The bubbles in boiling water are steam or vaporized water. The bubbles initially do not reach the surface of the billing fluid as the colder water away from the hot bottom cools the steam turning it back to liquid. WHen all the water is at 100oC the bubbles reach the top.


Is air less dense than water?

Of course it is. That is why bubbles rise to the top.


Why air bubbles rise in liquids?

Air is lighter than water, so the air bubbles just float to the top.


What causes bubbles to rise on top of water?

The gas inside the bubble is less dense than the surrounding water


Give three differences between evaporation and boiling?

evaporation happens at any temperature above melting point, boiling only at the boiling point. evaporation happens only at the surface, boiling happens throughout the liquid. boiling takes energy in (endothermic) to occur, while evaporation lets only the molecules with the highest kinetic energy out, leaving the rest of the water net kinetic energy, so evaporation is exothermic. the main difference is that boiling happens when heat is added from the bottom and evaporation is when heat is added from the top. For instance, when you boil water in a pot, it is being heated from the bottom, so steam bubbles form at the bottom and rise through the liquid, to the top. It would be evaporation if the heat was added from the top (no bubbles would form). the main difference is that boiling happens when heat is added from the bottom and evaporation is when heat is added from the top. For instance, when you boil water in a pot, it is being heated from the bottom, so air bubbles form at the bottom and rise through the liquid, to the top. It would be evaporation if the heat was added from the top (no bubbles would form).


How do bubbles of gas rise in a lemonade?

Carbon dioxide makes up the air bubbles, and carbon dioxide is lighter than lemonade, so the bubbles rise to the top.


Why the air bubbles become larger when it come to the top of water?

Air or CO2 bubbles tend to coalese as they rise and are being forced closer together by the containers shape. They can cling to a containers walls and group up as they rise.


What is inside the bubbles of boiling water?

hot air. ^^Close. It is actually steam or the gaseous form of H2O (water). As the water is heated it changes from a liquid to a gas. Since the heat is coming from the bottom (in a pot) and the top of the water is cooler, the gas forms bubbles.


Why is the boiling temperature taken as the temperature when bubbling just ceases?

Water is a liquid. When you heat it, it moves around a lot faster. When the water reaches 100 degrees Celsius, it turns into a gas called water vapour.This gas is lighter* than the water around it, so it rises to the top. Then it escapes into the air. As more and more of the water turns into gas, more of it disappears into the air. After a while, every last drop of the water will be gone. * Actually, the correct statement is that the gas is less dense than the water around it. Most of the bubbles start at the bottom, because that's where the heat is. The more heat you apply, the more bubbles you will get. The water is turning into a gas very quickly, and lots of bubbles form, and all try to rise to the surface at once. They push the water out of the way as they rise, and jump out of the surface. This is what we call 'boiling water'. So basically, the boiling point and below, the water stops moving so rapidly to produce bubbles.


How do you troubleshoot thermostat?

Take it out, should be somewhere on the engine side of the top radiator hose, undo the bolts on the housing and pour boiling water on it in a cup. It should open or for air bubbles when it is fully covered with boiling water.


How do you know if water is boiling?

There will be bubbles forming at the bottom of the water area that will float to the top. Water boils at 100 degrees celsius/273 degrees kelvin/212 degrees Fahrenheit.


When water boils what are bubbles?

When water boils, it turns to a gaseous state (water vapor). The bubbles are simply water vapor bubbles rising from the bottom to the top.

Why large bubbles form when water boils what are the bubbles made of?

When water boils, the bubbles are made of water vapor. Water is changing from the liquid phase to the gas phase, but it doesn't change all at once, so you get bubbles of gas inside the liquid. The phase change will happen first at the location where heating is taking place, so if you have a pot on a stove, the bubbles will form at the bottom of the pot, and then rise to the top.


Do the bubbles on a solar cover go on top or in the water?

The bubbles need to go in the water, facing the bottom of the pool.


Why white layer is formed while boiling water?

All the bubbles float to the top , this layer will grow if you don't remove it from the stove, it happens when tons of heat is applied


Why do bubbles last longer in cold water please help it's for a Science project?

Cold water is more dense than warm water. the bubbles rise to the top, and the density of the molecules that make up the wall of the bubble break up more slowly. DAN


Why do bubbles go to the top of the water?

because i told them to do so. ;)


Why do bubbles come from the ground when water is poured on it?

The water displaces air, which moves to the top. It comes up through the water layer, creating bubbles.


Why does boiling water 'bubble'?

The coolest part of the water is on the top of the pot. That's where the water is touching the air. Then obviously the hottest part is at the bottom where the water is closest to the heat source. Since heat makes water evaporate into its gas form, the bubbles are from the heated gaseous water from the bottom, making its way to the top, and out of the pot. If you were able to heat water evenly, or if you could have the heat source coming from above, there would be no bubbles. It would just slowly evaporate from the top as it reaches the right temperature.


Do fish have spit?

yes does bubbles at the top of the water are made by spit


Why are there bubbles in your water after a while of leaving it out?

the water is evaporating which pulls the water into a gas and the air bubbles take up at that space, come to the top, and dissappear so if its out long enough the bubbles might go away
