In which step of the four stroke engine cycle does the heat from the combustion reaction cause the pistons to move?
The heat from the combustion reaction causes the pistons to move during the power stroke in the four-stroke engine cycle. This is when the high-pressure gases from the combustion expand, pushing the piston downward.

Why the reaction of decomposition nitroglycerine occurs rather than combustion when a bomb containing nitroglycerine explodes on impact?
The decomposition of nitroglycerine occurs in a bomb explosion rather than combustion because the reaction is rapid and uncontrollable, releasing heat and gases at a faster rate than combustion. This rapid release of energy causes an explosive shock wave that shatters the container and creates the destructive force associated with explosions.
What is meant combustion?
Combustion is a chemical reaction that typically involves oxygen and a fuel source, resulting in the release of heat and light. It is an exothermic reaction in which the fuel is oxidized, producing combustion products like carbon dioxide, water, and other byproducts. Combustion is a fundamental process in many industrial and natural processes, from burning fossil fuels for energy to fire in nature.
What causes a reaction to be spontaneous and can you provide an example?
A reaction is spontaneous when it releases energy and increases the disorder of the system. This is determined by the change in Gibbs free energy (G) being negative. For example, the combustion of gasoline is a spontaneous reaction because it releases energy in the form of heat and increases the disorder of the system.

What causes the crankshaft to move?
The pistons, which in turned are moved by the expansion of gases caused by the combustion of fuel.
What is the reaction called when a mixture of gasoline and air encounters a spark and explodes?
The reaction is called combustion, specifically combustion of the gasoline-air mixture. The spark ignites the mixture, leading to a rapid release of energy that causes an explosion. This is the principle behind how internal combustion engines work in vehicles.
What causes Crankshaft verily move?
A crankshaft is responsible for converting the linear motion of the pistons into rotational motion, which propels the vehicle. It moves due to the forces exerted on it by the connecting rods attached to the pistons during the combustion process in the engine. This movement is essential for the proper functioning of the internal combustion engine.
What causes an increase of speed in a combustion reaction?
An increase in temperature, pressure, or concentration of reactants can cause an increase in speed in a combustion reaction. This provides more energy to break the bonds and allows the reaction to proceed faster.
What burns quickly and powers vehicles?
Petroleum distillates. Gas causes a combustion reaction in cars to produce energy.
What does oxygen react with that causes an combustion?
hydrocarbon
What is meant by the term internal combustion engine?
An internal combustion engine is where the pistons open up, gas goes in them and then they close. The pressure causes an explosive reaction from the gas. That reaction moves the piston up and down. The piston is connected to the transmission and drive train. The transmission is connected to the wheels and when the piston moves the transmission moves and so on. When the piston opens up again, the old gas leaves through the exhaust pipe and new gas goes into the piston repeating the cycle over and over again.
What causes oil in the exhaust?
Broke rings on pistons
