How do automobiles use the concept of thermodynamics?
Answers
Putting the ideal gas law, the piston, and adiabatic processes together with some fuel, we get an engine Then the gas expands adiabatically, called the “power stroke,” resulting in a sudden drop in the pressure and temperature. This part of the reaction is what gives power to the car.✔✔

Hey mate ☺️
✍️What is Thermodynamics?
➡️➡️Thermodynamics is a branch of science which deals with the study of heat and temperature and their relation to other forms of energy. It applies to a variety of science and engineering topics such as chemical, physical, and mechanical engineering. This branch was basically developed out of a desire to improve the efficiency of steam engines.
✍️How do automobiles use the concept of thermodynamics?
➡️➡️Putting the ideal gas law, the piston, and adiabatic processes together with some fuel, we get an engine! More details are listed in the pressure vs. volume diagram below, but basically, the fuel enters the cylinder and is adiabatically compressed. This means the volume decreases, the pressure and temperature increase. When compression is complete, the spark plugs ignite the fuel, which then increases the temperature and pressure at a constant volume. Then the gas expands adiabatically, called the “power stroke,” resulting in a sudden drop in the pressure and temperature. This part of the reaction is what gives power to the car. And finally exhaust fumes are released, decreasing the pressure a bit more, and the cycle starts over with a new batch of fuel.
