How can you change density of a substance?
You can change the density of a substance by changing its volume. Density is equivalent to mass over volume. So changing the volume affects density.
What is a property of a substance that can be observed without changing the identity of the substance?
Anything that has mass and occupies volume is called matter. In any substance its volume can vary but the mass is its intrinsic property. Mass of a particular substance remains the same anywhere we go but that is not the case for weight of a substance.
What happens to the overall mass of a substance when it changes state?
The overall mass of a substance remains the same when it changes state. The mass is conserved during physical changes like melting, freezing, vaporization, or condensation. This is because the number of atoms or molecules in the substance does not change during a change in state.
How does a physical such as mass or texture change without causing a change in the substance?
Ice melts to water if the temperature is high enough. This would change the texture but not the mass. It is difficult if not impossible to change the mass without changing the substance.

What would happen to density of a substance whose mass was cut in half?
If the mass of a substance is cut in half but the volume remains the same, the density of the substance would also be cut in half. This is because density is calculated by dividing mass by volume, so reducing the mass will directly affect the density without changing the volume.
The density of a substance is a state of matter of the substance?
Density is actually a physical property of a substance, representing the amount of mass present in a unit volume of the substance. It is not a state of matter but rather a characteristic that helps describe how closely packed the particles of a substance are.
Does changing the volume of a particular substance change its mass to volume ratio?
No, changing the volume of a substance does not alter its mass to volume ratio. The mass to volume ratio, also known as density, remains constant regardless of the volume of the substance. Density is a physical property that is intrinsic to the material and is not affected by changes in volume.
What is a substance no matter what state or shape is its mass per unit volume is what?
density
What is the energy per unit mass required to complete a phase change called?
The energy per unit mass required to complete a phase change is called the latent heat. It represents the energy needed to change the state of a substance without changing its temperature.
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.
