Is gasoline evaporated a chemical change

The correct answer is No

Explanation:

A chemical change is often characterized by the following

The evaporation of gasoline does not meet any of the characteristics above. When, a gasoline evaporates, it is converted from it's liquid form to it's gaseous form hence no new substance is formed, and if this conversion is done in a controlled environment, the gaseous form can be easily reversed back to it's liquid form by cooling. There is no chemical equation needed for this process since no new substance is formed.

Because of the reasons provided earlier, evaporation of gasoline is a physical change and not a chemical change.

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.
