Yes, it is possible to produce hydrogen and oxygen through electrolysis of water and burn them in an internal combustion engine to drive an automobile. However, the efficiency of this process is not very high due to energy losses during electrolysis and combustion, making it less practical compared to using hydrogen in fuel cells for vehicles. Additionally, the amount of hydrogen and oxygen produced would need to be sufficient to meet the energy demand of the engine, which may require large quantities of water and energy input.

Air stops behaving ideally at high pressures and low temperatures, where intermolecular forces and the volume occupied by the gas molecules become significant. At these conditions, the ideal gas law no longer accurately predicts the behavior of the gas.

The typical thinning allowance for SA-240 plates is about 0.33 times the nominal thickness of the plate. This allowance is made to account for any reduction in thickness that may occur during forming, rolling, or other fabrication processes.

Internal combustion engines burn fuel inside the engine to generate power, while external combustion engines burn fuel outside the engine and use the resulting heat to create power, such as in steam engines. Internal combustion engines are more common in vehicles due to their compact size and efficiency, while external combustion engines are used in specific applications like power plants and some marine propulsion systems.

In an internal combustion engine, the main chemical reaction is the combustion of a fuel (such as gasoline or diesel) with oxygen to produce carbon dioxide, water vapor, and heat. This process is typically carried out through a series of combustion reactions in the combustion chamber of the engine, resulting in the generation of mechanical energy used to power the vehicle.

The gasoline is mixed with air in the intake manifold of the engine. The intake manifold acts as a passage for the air to flow into the engine cylinders, where it mixes with the fuel before combustion.

During the combustion of gasoline in a car engine, the chemical energy stored in gasoline is converted into thermal energy through combustion. This thermal energy is then used to power the engine and drive the vehicle. While there may be some energy lost as heat or sound during combustion, the total energy of the system (including the car, gasoline, and surroundings) remains constant, thus conserving the energy of the universe.

A run back test is a procedure used in the oil and gas industry to assess the integrity of a well's casing by flowing fluid back up through the well. This test helps identify any leaks or issues with the casing and ensures that the well is properly sealed to prevent any potential hazards or environmental damage.

If the lawnmower is not electric powered then is is probably operated by an internal combustion engine (petrol or diesel.

Oddly enough, very early lawnmowers were steam powered, which means they were examples of external combustion engines.

Heat

Gaseous fuels such as natural gas, hydrogen, and propane are examples of fuels that are not in liquid or solid form. These fuels are often used in various applications such as heating, cooking, and transportation.

Quasi-static load refers to a load that is applied slowly enough that dynamic effects are negligible and can be approximated as a static load. This allows for simplified analysis of the structural behavior without needing to consider dynamic factors. It is commonly used in engineering to analyze the response of structures to slowly applied loads.

An internal combustion engine burns fuel internally to produce power, like in cars and motorcycles. An external combustion engine burns fuel externally to produce power, often using a separate heat source to generate steam, like in steam engines or some power plants.

Internal combustion engines generate mechanical energy through the controlled explosion of fuel and air inside the engine's cylinders. This mechanical energy is then converted into kinetic energy to power the vehicle.

Water injection works by injecting a mist of water or water-methanol mixture into the combustion chamber of an internal combustion engine. The water evaporates during the intake stroke, cooling down the air-fuel mixture and reducing the risk of detonation. This allows for increased ignition timing and boost pressure, resulting in improved engine performance and efficiency.

The stage that occurs just before ignition in an internal combustion engine is the compression stroke. During this stage, the piston moves upward in the cylinder, compressing the air-fuel mixture, preparing it for combustion when the spark plug ignites the mixture.

Iron will rust more quickly in the presence of hydroxide ions (OH-) because they increase the rate of oxidation of iron, leading to the formation of iron (III) oxide (rust). The hydroxide ions accelerate the reaction by increasing the concentration of reactants and facilitating the transfer of electrons in the redox reaction.

The weight of a locomotive engine can vary depending on its type and size. On average, a diesel locomotive engine can weigh between 100,000 to 200,000 pounds (45,000 to 90,000 kilograms), while a steam locomotive engine can weigh even more, up to 400,000 pounds (180,000 kilograms) or more.

No, the fuel is injected into the cylinders of an internal combustion engine, where it mixes with air and is ignited by a spark plug. The combustion process occurs inside the cylinders, generating power that drives the engine.

An internal combustion engine is a type of heat engine that generates mechanical energy by burning fuel inside the engine. A heat engine, on the other hand, is a broader category of engines that convert heat energy into mechanical work through various processes, including combustion, thermodynamic cycles, and heat transfer. In essence, all internal combustion engines are heat engines, but not all heat engines are internal combustion engines.

The internal combustion engine made possible the invention of automobiles, which revolutionized transportation by providing a faster and more convenient way for people and goods to travel long distances. It also played a critical role in the development of other industries such as aviation, agriculture, and manufacturing.

No, water cannot be used as a direct fuel in an internal combustion engine. However, water can be used in a process called electrolysis to produce hydrogen, which can then be used as a fuel source in internal combustion engines.

The source of thermal energy in an internal combustion engine is from the combustion of fuel (such as gasoline or diesel) inside the engine cylinders. The controlled explosion of the fuel-air mixture generates heat energy that is converted into mechanical energy to power the vehicle.
