as mass is the quantity of matter contained in a body
Mass is a Constant.
Particles of matter are always in constant motion.
The total mass remain constant after a chemical reaction.
I don't get the significance of the 'suitcase', but the mass of any object is constant, no matter where you take it.
It is possible for objects weight's to change, while its mass remains constant.
FALSE. Mass is a measure of the amount of matter within an object. Weight is the force of gravity on a mass. To get weight from mass, multiply mass by the gravitational constant of whatever planet you are on. MASS IS NOT WEIGHT!!!
Mass is the quantity of matter. Even though matter contracts the mass remains constant.
Mass of any chemical, in Chemistry, is always constant, no matter how much you change the conditions.
Yes.
No. Mass always remains constant
The dimension of mass is always [M].
Mass of any chemical, in chemistry, is constant, no matter what you do to it.
All matter
During chemical processes in a closed system the mass remain constant.
Particles of matter are always in constant motion.
The total mass remain constant after a chemical reaction.
Well, the Law of Conservation of Mass a.k.a the Principle of Mass/Matter Conservation says that the mass of everything that is closed to all matter and energy will always remain constant over time. ~ You can only tell if mass or matter is conserved by determining if it has a closed system or an open system ~ Mass or matter is only conserved in a closed system because a closed system is a system that cannot exchange matter with its surroundings, so to say that mass or matter is conserved by being "trapped" and will stay constant. I hope this helped!! XD
By definition, the mass of a certain amount of substance is a constant regardless of the state it is in. But you should realize that there are actually four, not three, states of matter. Matter in the ionized state is called plasma, which comprises 99.99% of all visible matter in the universe.
