Would the mass be the same in a sealed cup of water?

already exists.

Would you like to merge this question into it?

already exists as an alternate of this question.

Would you like to make it the primary and merge this question into it?

exists and is an alternate of .

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.

Is the mass in the air same as the mass in water?

Answer . \nNeed 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.

Why would your mass remain the same but your weight might change?

Mass is an intrinsic property of a substance while weight varies depending gravity. For instance the Moon has about 1/3rd of Earth gravity , so if you were weigh yourself on the moon you would way 1/3rd of what you do on Earth. However you mass would be the same and if you were to run into a wall ( Full Answer )

Is the mass of a cup of water greater than or less than a cup of sand?

The mass of a volume of a material depends on its density. A cup of water is likely to have less mass than a cup of sand, because the density of rock is generally much greater than water, and sand is fine particles of rock. Sand can be packed into a cup at different densities, but even if only ligh ( Full Answer )

How do you find the mass of water in a cup?

The easiest method is to weigh the water ... weigh the cup empty and full and take the difference ... and then divide the weight by the acceleration of gravity. Since the acceleration of gravity is well known on Earth, that method is accurate and easy, but it wouldn't work in another place where y ( Full Answer )

All samples of pure water have the same mass?

\nThere is a thing called heavy water. It is pure water that has a deuterium in it known as \nD20 instead of H20. It is pure but does not have the same mass.

How long would a clam last in the same cup of salt water?

The clam in the salt water would not last very long. It needs tobe in it's original habitat of water. . +++ . The poor little animal would probably die of suffocation as ituses up the oxygen dissolved in the water. Also, if the brine is ahome-made mix, its strength would probably differ markedly f ( Full Answer )

How much mass would be in a water molecule?

The cool thing about atomic masses listed on the periodic table is not only does it represent how many grams are in one mole of that element, but also how many amu (atomic mass unit)s one atom weighs. So, you can just add 2H + O = (2*1.00794) + (15.9994) = 18.0153 g/mol = 18.01528 amu. Then, you can ( Full Answer )

Would your mass be the same on the moon as on the earth?

Your weight would change because of the Moon's lower gravity, but your mass would remain the same because no matter is added or taken away from you Mass is the same, it is weight that is different due to the force of gravity. The mass of a body is a measure of how much matter it contains. Yes, ( Full Answer )

Which has bigger mass - cup of sand or cup of water?

A cup of water has the bigger mass. Why? Because one tiny droplet of water weighs more than one tiny gran of sand. Therefor more water put in a cup would weigh more than more sand put in a cup.

Why does water without ice stay the same in a plastic cup?

The plastic cups I can get have thin walls. This means the water without ice stays as water because any temperature changes to the water will not last very long. Insulated cups have thick walls so they will cool liquids cool and hot liquids hot

Is the mass of a cup of water greater than or less than a cup of sand why?

According to another Yahoo answer, the range of density of sand is 1.4 to 2.0 grams per ml. The density of water is defined at 1.0 grams per ml, so no matter what the volume or size of container, the sand will always be heavier. This DOES include the air space between the particles of sand.

Why a cup of sand have more mass than a cup of water?

Masses of chemicals (sand and water are both chemicals) are determined in part by their density. Density = Mass x Volume. Seen as the volume is the same (1 cup), density determines why each has a different mass. Water has a density of 1g per cm 3 . Therefore, sand must have a higher density. Sorry i ( Full Answer )

Does 1 cup of water have more mass than 1 cup of rocks?

The apparent density of rocks (excepting pumice, etc.) is greatest than the density of water; consequently the mass is greater for the same volume. --------- -- Therefore, some rocks must have more mass than the same amount of water has. ( ... a big part of the reason why they sink in water.) ( Full Answer )

Why would a brick on the moon have the same mass on earth?

Mass vs. Weight To understand the differences we need to compare a few points: 1) Mass is a measurement of the amount of matter something contains, while Weight is the measurement of the pull of gravity on an object. 2) Mass is measured by using a balance comparing a known amount of matte ( Full Answer )

Would a person's weight and mass be the same on the moon?

Weight would be different because the moon has less gravity then the earth. (astronauts can jump higher on the moon) Mass would be the same. I do not lose any mass if i go to the moon unless, you cut my arm off.

What is a seals mass?

The mass of a seal would differ on how large, long, and wide the seal was. It would also depend on a couple of other factors, but there is no one set mass for all seals.

Would you mass be less greater or the same on the moon?

Your mass is an invariant property of the matter from which you are made, it would therefore remain the same on the Moon or anywhere else in the Universe. However, your weight would be less on the Moon than on Earth because the gravity field of the Moon is less than that of Earth and your weight ( Full Answer )

Why would your weight be different on the moon but your mass will still be the same?

Your mass is a measure of the amount of stuff you're made of. It doesn't change. It's like the amount of money in your pocket. You can carry it around anywhere, and no matter where you are, it doesn't change. Your weight is a force between you and something else, caused by gravity. The strength of ( Full Answer )

Would the mass of an object be the same on the Earth and moon?

Yes, the mass would be constant but the weight would be different. The weight of an object would change on the moon because weight is defined as the downward pull of an object due to gravity. Since mass is not dependent on gravity, the mass of an object would stay the same no matter where you are. ( Full Answer )

Would the mass on mercury float on water?

Mercury would not float on water. This is because the density of Mercury (5427kg/m 3 ) is greater than the density of water (1000kg/m 3 ).

Why the mass and the volume of water are same?

Numbers are not "same" unless their units are the same. The massand volume are two different units of measurement. However, in terms of SI units,1 gram is the mass of 1 milliliter (volume) of water, and also of 1 cubic centimeter(volume) of water, because those units have been defined based on the m ( Full Answer )
