A water bubble consists of oxygen. Bubbles occur because of escaping air from liquids when heated. There is plenty of oxygen in water and that is why the bubbles are mostly oxygen.
Short answer: Pressure. Long answer: Pressure changes the boiling point of a substance. The higher the pressure, the higher the boiling point, and vice versa. For example, boiling water in the mountains is easier than boiling water at sea level. Note that boiling water is not necessarily hot. You can boil water at room temperature if the pressure is low enough (For example, using a vacuum generator)
Yes, boiling water to make steam is a physical change. This is because the water undergoes a change in state from liquid to gas without any change in its chemical composition.
Boiling water is a physical change because it doesn't change the chemical composition of the water molecules. The water molecules simply gain enough energy to break away from their liquid state and become a gas, without any new substances being formed.
No, a chemical change is when a substance and forms one or more new substances, it changes its composition. examples: changes in color production of gas formation of precipitate Boiling water is an example of physical change, it can be any phase change.
No, boiling water does not remove oxygen from the water.
Yes!
It is an event called vaporization.
During boiling the chemical composition is not changed.
Boiling it makes no difference to its acidity.
lol wow you dont need a piece of equipment to tell when water is boiling... you just watch the water as it heats up and when it starts to bubble its boiling... Ta -dah!
getting a saucepan, putting water in, letting it heat up on a turned on hob, wait for it to bubble and then add what your boiling. that's called boiling,
They are the same. When cold water heats up and bubbles that means it is boiling.
At the minute site of the formation of a bubble of boiling, we have some water turning instantaneously to steam. This has a much larger volume than water, and expands VERY rapidly. In this expansion, it forces some water away to make space for the bubble, and it is these forces of expansion, and the reaction to them, that causes the noise.
Boiling water is a physical change because it does not change the chemical composition of the water.
The two main factors that affect the boiling point of water are the atmospheric pressure and the presence of impurities in the water. As atmospheric pressure increases, the boiling point of water also increases. Impurities in water, such as salt, can raise the boiling point of water due to the change in the composition of the solution.
the composition of the litheosphere is lolly pops and bubble gum
the boiling of water is depends upon the outer pressure which acting on it, when water starts to boiling, that time bubble(water vapour) is produced and due to density differents it's goes upward. but when the pressure will decreases, that time it's easy to bubble to go upward direction, and its boils at a low temperature(below 100*c). and when the pressure increases that time the bubble need more force to go upward. so............................
