When a substance evaporates what happens to its mass?
Its mass is unchanged.
What type of reaction occurs and how does the mass of the object after rusting compared with its original mass?
1. Rusting is an oxidation reaction of iron.2. The mass of an object increase after rusting.
What type of reaction occurs and how does the mass of the object after rusting compare with its original mass?
Rusting is a chemical reaction known as oxidation. When a metal object rusts, it gains mass because the iron in the metal reacts with oxygen to form iron oxide (rust). The mass of the object after rusting will be greater than its original mass due to the addition of the iron oxide.
Is a rusting a substance?
Iron Oxide is rust; does that help?
What happens to density when you keep the volume the same and increase the mass of the substance?
When you keep the volume constant and increase the mass of a substance, the density of the substance will also increase. Density is calculated as mass divided by volume, so if volume stays the same and mass increases, density will increase as well.
When a substance expands what happens to its mass?
When a substance expands, its mass remains constant, as mass is a measure of the amount of matter in an object and does not change with volume. However, the density of the substance decreases because density is defined as mass per unit volume. Thus, as the substance expands and its volume increases, the same mass is distributed over a larger volume, resulting in lower density.
What happens to the mass of the volume is tripled?
If the volume is tripled, the mass will stay the same as long as the substance remains constant. Mass is an intrinsic property of matter and is not affected by the volume it occupies. The density of the substance will decrease as the volume increases.
What happens to the mass of gas when temperature is decreased by -273 degree celsius?
The Mass of a substance will not change with a reduction of temperature … even to -273C.
Why rusting is a chemical change and not a physical change?
Rusting is a chemical change because the metal is reacting with air and changing into a new substance.
What kind of a substance happens no matter what state or shape is its mass per unit volume?
density
Is rusting a chemical or physical property?
Rusting is a chemical property because it is irreversible. It changes the identity of the substance.
Is rusting car physical or chemical change?
A car Rusting is a chemicall change as a the iron in the car is converted into a different substance: iron oxide.
