Gas
A mixture of gasoline and air exploding is an example of a chemical reaction, specifically combustion. In this process, the gasoline (fuel) reacts with oxygen (air) in a rapid exothermic reaction, releasing heat and producing combustion byproducts such as carbon dioxide and water vapor.
Examples for exothermic change are burning of fuels or coal, burning of a fire cracker and glowing of an electric lamp.
'Exothermic' means to give out energy (heat). So combusting anything such as petrol/gasoline in a car engine is exothermic because it feels hot(heat) after while. In the lab. a lit Bunsen Burner is exothermic , because you are combusting a gas to make heat (energy).
Exothermic reactions release heat into the system, ie. heat is a product of the reaction and thus the products have less energy than the reactants and the change in enthalpy is negative.Exothermic reactions release heat. Like potassium into water
Both burning a log in a fireplace and burning gasoline in a car are examples of exothermic reactions. These reactions release energy in the form of heat and light as they occur. The heat and light produced during the combustion process are key to generating the energy needed to heat a room or propel a vehicle.
a gasoline engine is an Internal combustion engine
and internal combustion engine and a gasoline engine are the same thing.
No, the combustion of gasoline is not spontaneous. It requires a spark or heat source to initiate the reaction.
An example of a reaction that gives out a lot of heat is the combustion of gasoline in engines. This reaction releases a large amount of energy in the form of heat and light.
The source of energy for the non-hybrid automobiles is petrol or gasoline. The gasoline feeds into the combustion engine where it is actually the combustion that supplies the energy.
Gasoline is (or at least was) an abundant source of energy. Combustion of gasoline is an exothermic reaction that releases a significant amount of energy that can be harnessed. It's also cheap compared to other fuel sources, and has one of the highest energy return on investment (EROI - how much energy do you get based on how much you invest) ratings.
Combustion of gasoline in a car engine. Neutralization of an acid with a base, such as mixing hydrochloric acid and sodium hydroxide. Rusting of iron in the presence of oxygen and water.
