Use the principle of the Zeroth Law to explain what happens to air that enters the combustion chamber of an Internal Combustion Engine that has been running at its normal temperature. In particular in the induction stroke of a 4-Stroke engine.
Homework Answers
When cold air enters cylinder whose wall are hot starts to get hot or its temperature stars increasing by conduction and diffusion of heat from wall to air molecule adjacent to it . This process could be explained by zero law of thermodynamics .Zeroth Law of Thermodynamics states that if two bodies are each in thermal equilibrium with some third body, then they are also in equilibrium with each other. ... This says in essence that the three bodies are all the same temperature.
In the same way , all air molecules temperature reaches equal equilibrium temperature.

An internal combustion engine is running on octane, C8H18 (1) with stoichiometric amount of air. Both the air and fuel enter the engine at room temperature and the exhaust gas leaving the engine contain CO2, CO, H2, N2 and H20. The exhaust temperature is unknown. The brake power is measured and its value is known. It is also estimated that the rate of heat transfer amounts to say, 60% of the brake power; therefore the rate of heat transfer is...

Temperatures of gases inside the combustion chamber of a four-stroke automobile engine can reach up to 1000 °C. To remove this enormous amount of heat, the engine utilizes a closed liquid-cooled system that relies on conduction to transfer heat from the engine block into the liquid and then into the atmosphere by flowing coolant around the outside surface of each cylinder. Suppose that, in a particular 4-cylinder engine, each cylinder has a diameter of 9.00 cm, a height of 11.0...

Snell's Law and the Law of Reflection explain how light is redirected when it encounters a surface between two media. In the extreme, light may only reflect at a boundary, and go back into the medium it was in. More often, some of it reflects and some goes through. If the boundary is plane and flat, then these laws are easy to interpret. When the boundary is curved, they describe happens at every point on the surface. One of the...

Temperatures of gases inside the combustion chamber of a four‑stroke automobile engine can reach up to 1000 ∘ C. To remove this enormous amount of heat, the engine utilizes a closed liquid‑cooled system that relies on conduction to transfer heat from the engine block into the liquid and then into the atmosphere by flowing coolant around the outside surface of each cylinder. Suppose that, in a particular 5 ‑cylinder engine, each cylinder has a diameter of 8.25 cm, a height...

A friend passionate about cars mentions that Toyota has developed an engine with a thermal efficiency of 40% which is an extraordinary accomplishment! 1) Supposing this engine is ideal and based on the Carnot cycle, and also assuming that the cold reservoir temperature is 300 K, what is the hot reservoir temperature to meet the stated efficiency? You mention your result to this friend who points out correctly that the temperature of the hot reservoir would essentially be the temperature...

2. Use Snell's law (n, sin = n, sine,) to explain why , is greater than 0 in Fig. 2. Total Internal Reflection When light passes from a medium of large refractive index into one of small refractive index --- for example, from water to air --- the refracted ray bends away from the surface normal, as shown in Fig. 2. As the angle of incidence increases, the angle of refraction also increases. When the angle of incidence reaches a...
