The burning of gasoline is a chemical change. The evaporation of gasoline is a physical change. This is a physical change because it is a change in state of matter (from liquid to gas).
Gasoline is a mixture not a chemical compound.
Gasoline being poured into a tank is not a chemical change.
Gasoline burning is an oxidation reaction, a reaction with oxygen.So, burning is a chemical change. And fire was the most important discovery of human beings.
Yes, gasoline undergoes a physical change when it evaporates before it burns. This change does not alter the chemical composition of the gasoline.
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.
No. 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.
Freezing of water and evaporation of gasoline are physical changes because they involve a change in physical state without altering the chemical composition of the substances. Rusting of a nail is a chemical change as it involves a chemical reaction between the iron in the nail and oxygen in the air to form iron oxide.
All changes of state are physical changes. Nothing happens to the molecules of gasoline when it evaporates, they just get further apart.
Gasoline evaporation is a physical process.
E- 10 has about the same volatility rate as gasoline.
No, the rate of evaporation will decrease as pressure is increased.
Gasoline is usually a liquid. Although it has a low evaporation Point and easily turns into vapour.
Gasoline can evaporate at temperatures as low as 32 degrees Fahrenheit, but the rate of evaporation will be much slower compared to warmer temperatures. Factors such as humidity and ventilation can also affect the evaporation rate of gasoline at this temperature.
Gasoline burning is a chemical property because it involves a chemical reaction where gasoline is combined with oxygen to produce heat, light, and exhaust gases. This process results in a change in the chemical composition of the gasoline.
there are chemical energies in gasoline
Gasoline is a mixture not a chemical compound.
