Yes.
Chemical change
Yes, it is.
yes
it is a chemical change! (sexy right?;)
The conversion of gasoline to carbon dioxide when it is burned is a chemical change, as it involves the breaking and forming of chemical bonds. This process releases energy in the form of heat and light.
It is not. Gasoline is not energy. Rather, it HAS energy.If gasoline is burned or otherwise combines with oxygen, energy is released. This type of energy (related to how atoms are connected with one another) is called "chemical energy".
Gasoline being poured into a tank is not a chemical change.
Gasoline is an example of stored chemical energy. The hydrocarbons in gasoline store energy in their chemical bonds, which is released when the fuel is burned to power engines.
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.
The chemical energy becomes heat energy when the gasoline is burned. Oxidation releases chemical energy stored in the carbon-carbon bonds of fossil fuels and in the diatomic bonds of O2.
Yes, gasoline undergoes a physical change when it evaporates before it burns. This change does not alter the chemical composition of the gasoline.
