Is the change of identity a physical or chemical property?
If you mean a change in chemical identity, that would be a chemical change.
Why would frying an egg be a physical change instead of a chemical change?
Frying an egg is a chemical change.
Is Pungent odor a physical or chemical change?
It would be a physical change because it is not changing the chemical composition.
Is mixing milk and cream to a physical or a chemical change?
It would be a chemical change, because if it was a physical change it would stay the same substance, but in a chemical change you mix 2 different substances to get a new substance.

Is wax melting chemical or physical change?
This is a physical change, not a chemical change! It is because all the wax is still all there as for if it was a chemical change it would be all gone!Physical. Its physical state changed from solid to liquid. It's chemical make up remains the same.Melting wax is a chemical change because a new substance is forming. Trust me im intelligent and we just learned this in science.physical change :)It is a chemical change because it gives off heat even when it is burning. heat is one of the signs that tell whether it is physical or chemical change. The signs are heat , light's ,gas,discolor.Melting was would be a physical change-- no chemical reaction occurs when something melts or boils. A burning candle is a chemical change, both can occur at the same time.
Pouring milk in you r oatmeal - Physical or chemical?
It would be physical change because the substance doesn't change. Signs of chemical changes would be absorbing, liberating (releasing) heat, fizzing, changes of color,or giving off light.

Is the change of identity a physical or chemical property?
If you mean a change in chemical identity, that would be a chemical change.
Is the conversion of two compounds into a solution a chemical change?
Not necessarily. There's something called the enthalpy of mixing which can be responsible for lowering the temperature when two substances are mixed even if no chemical reaction occurs. It may also be an endothermic reaction; if there are other signs of a reaction (formation of a precipitate, evolution of a gas, color change, etc.) then it probably is a chemical reaction.
Does a candle or a campfire have more energy?
a campfire would have bunches more energy
What property is one that involves the production of a new substance?
This would be a chemical change. The other type would be a physical change. In a physical change the identity of the material does not change.
If leaves producing oxygen a chemical or physical change?
That would be a chemical change.
Is flammable a chemical or a physical change?
Something that burns or is flammable would be a chemical change.
Is evaporated gasoline a chemical change?
No, it would be a physical change. During a chemical change, substance(s) are changed into different substances. An example of a chemical change would be the rusting of iron but a physical change would be freezing water; or in this case, evaporation.
