The mass remain unchanged, only the density is variable.
No, solids do NOT change mass when they change form into a liquid. The only way the mass can be changed is if the substance goes from a liquid to a vapor or gaseous form.
The TOTAL mass of the sample stays the same, but keep in mind that you can only measure it accurately if you can keep the sample confined, which can be difficult when changing a liquid to a gas. When heating a gas, it usually expands (or increases pressure in a rigid container).
Density is the mass of a substance divided by the volume of that same mass of substance.
Grvity affects everything with mass. Gas has mass. The Earth's atmosphere, and every part of the sun, are gaseous. They exert gravitational force, and they have gravitational force exerted on them.
The mass of a given volume of a substance depends completely on the density of the substance being analyzed. Density = Mass / Volume
Not at all.
no change in mass
The answer to that depends on the density of the substance in question.For instance the volume of 68 grams of Lead would be smaller than the volume of an equivalent mass of gaseous hydrogen.
No, solids do NOT change mass when they change form into a liquid. The only way the mass can be changed is if the substance goes from a liquid to a vapor or gaseous form.
The mass is basically NOT affected by gravity. The weight IS affected, and it is equal to mass x gravity.
The TOTAL mass of the sample stays the same, but keep in mind that you can only measure it accurately if you can keep the sample confined, which can be difficult when changing a liquid to a gas. When heating a gas, it usually expands (or increases pressure in a rigid container).
Density is the mass of a substance divided by the volume of that same mass of substance.
mass by difference is an indirect way to find the mass of an object. For example, if you know the mass of a 'beaker and the substance in it' and the 'mass of the beaker', you can determine the mass of the substance by subtracting (mass of beaker + substance) - (mass of beaker)
When we divide the mass of a substance by its volume we get its density.
It cools and condenses
Grvity affects everything with mass. Gas has mass. The Earth's atmosphere, and every part of the sun, are gaseous. They exert gravitational force, and they have gravitational force exerted on them.
because mass is the total amount of quantity of a substance. mass helps to retain the substance
