Assuming that it is a half litre bottle of water, the water would have a mass of 500g so the bottle would have a mass of 95g. However it might be a pint bottle of water, in which case the water would have a mass of 568g, leaving the bottle with a mass of 27g.

Objects float if they displace more than their own mass. This means that if when they are put into a liquid the mass (weight) of the volume of the liquid that "has to get out of the way" is greater than the mass of the object, it will float.An empty glass bottle floats in water because the bottle is filled with air, yet the bottle's shape keeps water out and the mass of the volume of the displaced water exactly equals the mass of the bottle (and the air inside).

Calculate the amount of water in a gallon of water. The mass of the steam will be exactly the same as the mass of the water. No mass should be lost.

The mass will depend upon the size of the water bottle. The density of water is 1, so you use the equation density=mass/volume.

The mass of liquid water will equal the mass of steam,

bc water has a greater surface area which makes the mass larger

No. Mass is not created or destroyed. The mass of the steam is equal to the mass of the water that evaporated to make the steam, so their weights are equal.

Yes.

This simply means in a steam/water mixture the proportion of steam to the total mass of steam and water. This is relevant to BWR's which produce a steam/water mixture at the core outlet.

The liquid mass is partly converted to a gas (steam, water vapor), so if this escapes, the mass is no longer there. The steam can, however, be captured and condensed, and used again (as in steam engines).

Yes it dose. Its just not very dense. If you boil water and can some how capture the steam the weight it the total weight of the steam and water that is left will have the same weight as the water you started with. (Mass can not be created or Destroyed)

The weight of the bottle with the water minus the mass of bottle gives the weight of the water present.Mass/Volume=Density,therefore weight of the water/density gives the volume of water present in the bottle which is nothing but the volume of the bottle itself.

Density equals the mass divided by the volume. Therefore the greater the mass the greater the density of the object. Salt water has a higher mass per volume than fresh water because the NaCl molecules have a greater mass than the H2O molecules.

If all the water boils off, the mass of the steam will be 100 grams. Matter cannot be created or destroyed.

Water has a larger surface area on the earth. Land has a greater mass.

Fill it with water. Then poor the water into a container. Either meausre directly the amount of water (if the containor can do that) or measure the the mass of the container before and after. The difference is the mass of the water and (it in grams) is equal to the ml of water that was in the bottle.

Because there's very little water in it that requires heating. Each molecule requires heat to raise its temperature, and to make the phase transition to water vapor (steam). The greater the mass of the water, the greater the total energy required to heat it.

The mass of the water The number of molecules

The mass of the bottle will remain the same whether it's full or empty however, the weight will change.

err, yes, because: bottle mass + soda mass > bottle mass

This depends on the mass.

For a given mass, steam will have more energy than water. The difference is called the 'heat of vaporization'. One thing to be carefuls about, of course, is that a given mass of steam will occupy much more volume than the same mass of water.

Yes

water has less density than lead. Mass depends on its volume
