What are the different types of chemical reactions? : 

What are the different types of chemical reactions? Exothermic Reaction Endothermic Reaction Catalyst Enzymes

What is a combustion reaction? : 

What is a combustion reaction? The sequence of exothermic chemical reactions between a fuel and an oxidant accompanied by the production of heat and conversion of chemical species.

What is the fire triangle? : 

What is the fire triangle? A simple model for understanding the ingredients necessary for most fires. The triangle illustrates a fire requires three elements: heat, fuel, and an oxidizing agent (usually oxygen).

What is activation energy? : 

What is activation energy? The minimum amount of energy required to convert a normal stable molecule into a reactive molecule.

Why is heat/energy a necessary part of the fire triangle? : 

Why is heat/energy a necessary part of the fire triangle? Without sufficient heat, fire cannot begin, and it cannot continue.

How is the cooktop of your stove a real-life example of a fire triangle? : 

How is the cooktop of your stove a real-life example of a fire triangle? The cooking gas inside the stove helps the fire light up and get hot on the stove when we use it.

What is a combustion engine? : 

What is a combustion engine? Any of various types of engines driven by energy produced by combustion.

How does a combustion engine work? : 

How does a combustion engine work? An internal combustion engine contains a closed cylinder in which combustion takes place. It pushes piston to and fro. Piston is connected to fly wheel through crank shaft.

In terms of combustion, how are NASCAR engines different from street car engines that allow them to operate at much higher speeds? : 

In terms of combustion, how are NASCAR engines different from street car engines that allow them to operate at much higher speeds? NASCAR engines don’t contains all the parts of a regular engine that a regular street car has.

How does nitrous oxide help engines perform better? : 

How does nitrous oxide help engines perform better? When you heat nitrous oxide to about 570 degrees F, it splits into oxygen and nitrogen. So the injection of nitrous oxide into an engine means that more oxygen is available during combustion. Because you have more oxygen, you can also inject more fuel, allowing the same engine to produce more power.
