EXPLAIN the industrial applications of IC engine?

Internal combustion engines (ICE) are the most common form of heat engines, as they are used in vehicles, boats, ships, airplanes, and trains. They are named as such because the fuel is ignited in order to do work inside the engine.[1] The same fuel and air mixture is then emitted as exhaust. This can be done using a piston (called a reciprocating engine), or with a turbine.

The ideal gas law

Internal combustion heat engines work on the principle of the ideal gas law: . Raising the temperature of a gas increases the pressure that makes the gas want to expand.[1] An internal combustion engine has a chamber, which has fuel added to it which ignites in order to raise the temperature of the gas.

When heat is added to the system, it forces gas inside to expand. With a piston engine, this causes the piston to rise, and with a gas turbine, the hot air is forced into the turbine chamber, turning the turbine . By attaching the piston or turbine to a camshaft, the engine is able to convert a portion of the energy input to the system into useful work.[2] To compress the piston in an intermittent combustion engine, the engine exhausts the gas. A heat sink is then used to keep the system running at a consistent temperature. A gas turbine, which uses continuous combustion, simply exhausts its gas continuously rather than in a cycle.

the army does care about its soilders sir i think yout getting off on the wrong foot sir you need to respect our country were keeping the peole that want to d harm towards you out. so dont go saying we don't care cause we do
