The density of an substance varies with samples of that substance?
that is false because a density is a physical property and as u know physical property can't be changed
Is the odor of gasoline a chemical property?
liquid to gas formation is physical change
True or false the density of a substance is the same for all samples of substance?
False :3
Is a tree that is cut into boards at a sawmill a chemical change?
Sawing a board in half is not an example of chemical change. It is an example of a physical change. Physical changes on a substance do not change the substance. When you saw a board in half, the two halves of the boards are still boards- they're not anything else.
Is it true that if a physical change that occurs when a substance changes composition by forming one or more new substances?
No. That is a chemical change. In a physical change, their is no change in chemical composition forming one or more new substances.

True or false a boiling point is a chemical property of a substance?
Since boiling results in change in the physical properties of a substance (no change occurs in the chemical composition), boiling can be termed as a physical phennomenon (property). Whereas boiling point is a part of this property i.e a temperature at which the substance changes into vapors.

Is color and hardness examples of chemical properties?
This is False. The colour has to change to be a chemical change/property. If it stays the same, it is physical. Hardness is an example of a physical property. (ex. If I melt a piece of hard steel, it will become soft, liquid probably, but it isn't hard anymore, this change is reversible, therefore a physical change/property)
Is it true are false that a physical change of a substance changes its chemical makeup?
true
Is it true that Physical changes are often accompanied by changes in color or odor.?
No. It is false. Physical changes are not accompanied by changes in color or odor.
What is it true or false. Corrosion is a physical property of metals.?
False. Corrosion is a chemical property. When a metal corrodes, it reacts with its environment to produce oxides, hydroxides, and other types of corrosion.
Is it true that Physical changes are often accompanied by changes in color or odor?
No, a chemical change is usually accompanied by a change in color or odor. A physical change is a change that is the same substance before and after and usually accompanied by a change in state of matter (evaporation, condensation, melting, freezing, sublimating, etc).
During a chemical change the form of a substance is altered but not its identity true or false?
The statement is false: A chemical change of a substance is defined as a change in which the substance is not the same substance after the change as it was before.
True or false Density is the weight per volume of a substance?
Hmmm... technically false. Density is mass/volume - it is an intrinsic property. Weight is subjective to the force of gravity, while density is not.
Is it true or false a colligative property is a physical property affected by the type of the particles not the number of particles?
to tell you the truth no one is gonna answer you. in fact i need that answer right now. \
