What does it mean to say that mass is conserved during a physical change?
Saying that mass is conserved during a physical change means that the total mass of the substances involved remains constant before and after the change. This principle is a fundamental aspect of the law of conservation of mass, which states that mass can neither be created nor destroyed in a chemical reaction or physical change, only transformed into different forms.
Does the mass of an oil change its density?
No, the mass of an oil does not change its density. Density is a physical property of a substance that remains constant regardless of the amount or mass of the substance. It is defined as mass per unit volume.
Does a substance change mass if it changes physically?
No. Mass is a measure of how much matter is in an object, and that does not change when the matter changes states. The matter will either contract or expand, depending on the current state and the state to be reached, but that does not change how much matter is in the object.
What are two ways mass can change?
Mass can change by adding or removing material from an object. This can either increase or decrease the mass of the object. Additionally, mass can change through physical or chemical reactions where the composition of the object is altered.
What happens to the density of a fluid if you change its mass but keep the volume constant?
If you change the mass of a fluid while keeping the volume constant, the density of the fluid will change. Density is calculated as mass divided by volume, so if the mass changes but the volume stays the same, the density will increase if the mass increases and decrease if the mass decreases.
What happens to mass during chemical and physical change?
it stays da same
Is mass a chemical change or physical change?
Mass is neither a physical nor chemical change; however, it is a physical property of matter.
Does mass change in a physical change?
In this case mass doesn't change.
What is it called when there is no change in mass?
It is a physical change.
What physical change happens to the water from the dye solution?
The physical change that happens to the water from the dye solution is that it gets colored. The water molecules themselves do not change chemically, but they become colored by the dye molecules that dissolve in the water.
What kind of change happens when a brick crumbles Physical or chemical?
It is a physical change.
What happens to the mass of 40g of i c e cubes when they melt?
Nothing. Ignoring evaporation, the mass stays the same as ice turns to water. It's a physical change, not a chemical.
What happens in a chemical change but not in a physical?
Molecules permanently change. In a physical change the effects are reversible.

What change happens when a metal fork rusts?
physical change
When a popsicle melts does the mass inreases?
No. A physical change like melting does not make something's mass change.
How does physical change and chemical change affect mass?
In a physical change, the mass remains the same since it involves a rearrangement of particles without changing their identities. However, in a chemical change, the mass can change due to the formation or breaking of chemical bonds, resulting in a gain or loss of mass.
