It is a chemical change because the temperature changes, light is emitted, and there is a change in smell or taste. 3 signs of a chemical change.
Yes, trees are a physical feature of the environment. They are living organisms that have a distinct structure and presence in various landscapes. Their presence contributes to the overall physical makeup of ecosystems and habitats.
Human attraction encompasses a combination of physical, emotional, and intellectual factors that draw people to one another. Physical attraction specifically refers to the initial attraction based on someone's physical appearance.

No, it is a physical change. The water and gasoline retain their chemical and physical properties.
Yes, gasoline undergoes a physical change when it evaporates before it burns. This change does not alter the chemical composition of the gasoline.
melting is a physical change. freezing is also a physical change. the only thing that changed was the state of matter. a chemical change for example is buring, the substance changes to co2 and h2o.
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.
This is a physical change.
No, combustion of gasoline is a chemical change because it involves a chemical reaction between the gasoline and oxygen to produce carbon dioxide, water, and heat. A physical change involves a change in the physical state or appearance of a substance without altering its chemical composition.
Gasoline evaporation is a physical process.
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.
