Why entropy decreases with the increase in temperature?
Answer: The relation is ds = dQ/T Entropy is inversely proportional to the temperature so as temperature increases, entropy decreases.
-
How air conditioners work in cars?
Answer: Air conditioners are based on the principles of evaporation and condensation and then compression and expansion. The hot air of the car is removed by the process of evaporation and then the condensation of the evaporated air takes places which is then further compressed by the compressor and then finally expanded to us in the…

What will happen if someone adds oil to the fuel of four stroke bike engine?
Answer: This will result in damaging of the engine faster. Adding oil will lead to the higher wear and tear of the cylinder liner, piston and damage to the piston. It will lead to abnormal combustion and knocking and detonation. Dark smoke and abnormal sounds will be generated by the engine. One should not mix oil…

Why big tyre used in rear of Tractors?
Answer: Tractors have big rear tires because, the larger the surface area of the tractor’s wheels touching the ground, the more pulling power you have. Like how tractor pullers have large tires. Another reason is that the tractor doesn’t have to operate at a higher speed to get the same ground speed with larger tires. Gear…

What is the difference between BS2 & BS3 engine?
Answer: IN BS2 there is No catalytic converter to reduce formation of co and HC whereas in BS3 catalytic converter is available to reduce the formation of HC and CO. So less mission of HC and co will take place in BS3
-
How Trains take turns, though there is no any differential?
Answer: Purpose of the differential is to enable vehicles to take turn, by allowing both the wheel to rotate with different speed. This is required when wheels, like in car, are connected with same axle. Interestingly, wheel in trains are not connected with the axle, they are independent and hence can take turns without ant differential.…

By mixing oil in fuel of four stroke bike will it damage engine, performance? If not than what happen?
Answer: Yes, absolutely. It leads to higher wear and tear incylinder liners, piston and damage of the piston. It evenleads to knocking and detonation where abnormal combustion appears and dark smoke and harsh sound will be produced by the engine.

What is oil grade SAE stands for?
Answer: “SAE” stands for “SOCIETY OF AUTOMOTIVE ENGINEERS” (USA).

What is the working principle of hydrostatic propulsion system in a tractor?
Answer: It depends on Pascal law. As the pressure in the system is the same, the force that the fluid gives to the surroundings is therefore equal to ‘pressure × area’. In such a way, a small piston feels a small force and a large piston feels a large force
