Consider the burning of gasoline and the evaporation of gasoline which process represents a chemical change and which represents a physical change?
The burning of gasoline represents a chemical change because it involves a reaction with oxygen to produce heat, light, and new chemical compounds. On the other hand, the evaporation of gasoline represents a physical change as it involves the gasoline changing from a liquid to a gas without any change in its chemical composition.
Is breaded toast a physical or chemical change?
Toasting bread represents a chemical change.
Is a spoiled pear a physical or chemical change?
Spoiled food of any kind represents a CHEMICAL change.
Is slicing turkey a physical or a chemical?
Slicing turkey represents a physical change, not a chemical change. The chemical composition of the sliced turkey is identical to the chemical composition of the intact turkey. Only a physical change has taken place.
Is humidity a physical change?
Humidity itself is not a physical change, but a physical property of the air that can change based on temperature and pressure. Humidity represents the amount of water vapor present in the air, and can vary without altering the composition of the air itself.
