No
Nope.
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.
No. Evaporation is a physical process.
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.
It is chemical change... It is also physical change........Thats because the appearance also changed.Its a chemical change because when something is evaporated, these steps include chemicals.
Gasoline being poured into a tank is not a chemical change.
The burning of gasoline in a car is a chemical change because it involves a reaction between the gasoline and oxygen to produce new substances (carbon dioxide, water, and heat). This results in a change in the chemical composition of the substances involved.
Yes, gasoline undergoes a physical change when it evaporates before it burns. This change does not alter the chemical composition of the gasoline.
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.
Chemical change
Chemical change
The burning of gasoline is a chemical change because it involves a reaction with oxygen from the air to produce carbon dioxide, water vapor, and energy. This process cannot be easily reversed to recover the original gasoline molecules.
