Because there is a law of nature that says that matter (mass) can neither be created nor destroyed.
However, Einstein proved that mass and energy are actually the same thing (E=MC2), so mass can be turned into energy and energy can be turned into mass.

What of a substance remains constant regardless of where you go in the universe?
Mass.
Does the mass of water increase when it is frozen?
No, the volume it occupies and the density will change however the mass will remain constant
Does mass remain the same when matter contracts?
Mass is the quantity of matter. Even though matter contracts the mass remains constant.
How does amplitude of a pendulum affect frequency?
it doesnt affect the amplitude as the mass and length remain constant
What happens to temperature as energy is added to a substance that is changing state?
The temperature remain constant during the phase changing.
Which variables must be kept constant for Boyle's law to hold?
The temperature must remain constant.
Why does a substance have a constant flow rate if all variables remain constant?
because i have bstl
Does mass remain constant?
Yes, Mass remains constant because the definition of mass does not mean weight. Mass means the amount of room and object takes.
Why the mass of a substance is constant everywhere?
Because the mass is not dependent on the gravitational influence.
What of a substance remains constant regardless of where you go in the universe?
Mass.
How heavey os one pound on venus?

what is the law of conservation of mass?
During chemical processes in a closed system the mass remain constant.
If the mass of sodium chloride dissolves in H2O does the mass increase or decrease?
The mass of sodium chloride remain constant.
What is all matter is made of atoms and molecules that are in constant?
The total mass remain constant after a chemical reaction.
When a substance changes from a solid to a liquid its density normally decreases. What is happening to the substance's mass and volume to cause this decrease in density?
A decrease in density would indicate a reduction in mass relative to the volume. If the mass decreases but the volume remains the same or increases, then the density would decrease.
How is the mass of a gaseous substance affected after it condenses?
The mass remain unchanged, only the density is variable.
Does the total amount of mass during a chemical reaction increase?
The total mass of the compounds remain constant.
