Is gasoline being evaporated a chemical change?
It's both a chemical change and a physical change. Gasoline doesn't explode. In order for there to be an explosion, the combustion must happen in a sealed container. The gasoline combusts with oxygen in the atmosphere to form carbon dioxide, water vapor, nitrous oxides, and soot, along with a lot of heat. The liquid gasoline produces mostly vaporous products, and in a sealed container, will generate very high pressures. The high pressure will cause the container to explode.
Is using scissors to cut paper a physical or chemical change?
It is a physical change, as the chemical integrity remains the same.
When water is put in the freezer to make ice is it a physical change or a chemical change?
A physical change.
When water evaporates into a stream is it a physical change?
Physical change. The chemical formula of the steam still remains as H2O.
When limestone is crushed is it a physical change?
Yes, crushing limestone is a physical change. This is because the chemical composition of limestone remains unchanged during the process of crushing. The size and shape of the limestone particles may change, but the chemical makeup remains the same.
When limestone fizzes when acid is added is physical or chemical change?
chemical change

Is dissolving soup in a water a chemical or a physical change?
A physical change - since the chemical composition of the soup remains unchanged.
When water is put in the freezer to make ice is it a physical change or a chemical change?
A physical change.
Dry ice converts directly to a foggy gas without melting physical or chemical change?
Dry ice is simple CO2 and at 1atm goes from a solid to a gas. Dry ice is solid Carbon dioxide and it changes physical state to gaseous Carbon dioxide without going through a liquid phase, this process of turning directly from a solid to a gas is called sublimation. As the chemical composition of the Carbon dioxide remains unchanged the change is entirely physical.
Is candle wax melting chemical or physical change?
It is a physical change, from a solid to a liquid. The chemical composition of the wax remains unchanged.
Is when it remains unchanged in the presence of nitrogen chemical or physical?
When something remains unchanged in the presence of nitrogen is it a physical change?
What are the factors classified as chemical and physical reaction?
a chemical change alters the materials chemical makeup and physical change just alters the appearance and it remains with the same chemical composition
What happens to the energy of the universe during physical or chemical process?
During any chemical or physical process, the energy of the universe remains unchanged.
When ice melts at room temperature is it physical property or chemical property?
physical property because the chemical makeup of the ice remains the same
