Too vague a question. If you mean, does sealing the cup change the mass, then no it does not change the mass of the water, though the sealing material would add its own mass to the total.

What happens to mass of ice when it melts in a sealed container and why?

When ice melts in a sealed container, the mass of the system remains constant. This is because the total mass of the water (from the melted ice) and the remaining ice adds up to the same mass as the original ice. The melting process simply changes the state of the matter from solid to liquid, but does not alter the total mass within the closed system due to the conservation of mass principle.


After the water is boiled its mass stays the same yes or no?

After water has been boiled, its mass will stay the same.


All samples of pure water have the same mass?

Yes, all samples of pure water have the same mass because the mass of water is determined by its chemical composition, which consists of two hydrogen atoms and one oxygen atom. This means that regardless of the volume or container, the mass of pure water remains constant.


Does solid water have the same mass?

Need more data to answer. Are you talking about the mass of an object, neither air nor water, being the same when in the air or in the water? Yes. Are you talking about the total mass of all the air on earth compared to the total mass of all the water on earth? Definitely not.


Does frozen water and liquid water have the same mass?

Yes, frozen water (ice) and liquid water have the same mass when measured under the same conditions. The mass of water does not change when it freezes; however, its volume does change due to the difference in density between ice and liquid water. Ice is less dense than liquid water, which is why it floats.

How would mass change if you place a burning candle in a sealed container?

The mass would remain the same. In a sealed container, the products of burning (such as soot and water vapor) are not able to escape, so the mass inside the container would stay constant due to the law of conservation of mass.

How is boiling water in the law of conservation of mass?

Boiling water follows the law of conservation of mass, which states that mass cannot be created or destroyed, only transformed. When water is boiled, it is converted into water vapor, which still contains the same amount of mass as the liquid water. The total mass of the water and water vapor remains constant throughout the process.


When an object is submerged will it weigh less or have less mass?

Objects under water seem to weigh less but they have the same mass as they would out of water.


How many pounds of water does it take to produce five pounds of steam?

In a sealed chamber with no loss of mass, five pounds of water plus sufficient heat will produce five pounds of steam. The mass of the water remains the same, regardless of its state. Freeze it, and you'd have five pounds of ice instead.


Does the mass of a ice cube stay the same after being in a sealed box and left in the sun with only some droplets left?

Whatever you do with an ice cube, and whether or not it all stays where you put it, the total mass is the same at any time you decide to measure it. If you put it in a box, and put the box out to broil in the sun, then there may be only a few droplets of water on the bottom of the box after a while, but if the box is truly sealed, then the rest of the ice cube is still inside it, most likely in the form of water vapor (steam) at elevated pressure. Add that all up along with the droplets, and you have the same mass that you started with. If you don't, then your box is not really sealed, and some of it got out.


After the water is boiled its mass stays the same yes or no?

After water has been boiled, its mass will stay the same.


What is the mass of 300 L?

There can be no sensible answer. Litres are a measure of volume, not of mass. Consider a litre of air: what would its mass be? Next consider a litre of water. It will not have the same mass as the air.


What is the mass of one liter of water on the moom?

The mass of one liter of water is about one kilogram. It does not matter if you check it on the moon, on the Earth, or on Jupiter.Weight, on the other hand, is different in those three places, but the question did not ask for weight, it asked for mass.


When water evaporates its mass decreases?

no the mass remains the same


Are there different water masses?

pure water has the same density, and the same mass
