Carnot cycle is a theoretical thermodynamic cycle that operates between two heat reservoirs.
It consists of four reversible processes: isothermal expansion, adiabatic expansion, isothermal compression, and adiabatic compression.
It is used to determine the maximum efficiency that a heat engine can achieve.
The efficiency of the Carnot cycle depends only on the temperatures of the two reservoirs.
It is named after French ph...
Petrol engines use spark ignition while diesel engines use compression ignition.
Petrol engines have higher RPM and power output compared to diesel engines.
Diesel engines have higher torque and fuel efficiency compared to petrol engines.
Petrol engines are lighter and quieter compared to diesel engines.
Examples of petrol engines include those used in cars, motorcycles, and small aircraft, while diesel engines are commonl
Adiabatic process is a thermodynamic process where no heat is exchanged with the surroundings.
Adiabatic process occurs when a system is thermally insulated from its surroundings.
In this process, the internal energy of the system changes due to work done on or by the system.
Examples of adiabatic processes include the compression or expansion of a gas in a piston-cylinder system.
Adiabatic cooling occurs when air rises in...

A mutex is a synchronization primitive that ensures only one thread can access a resource at a time.
Create a mutex object using the appropriate library or language-specific function.
Lock the mutex before accessing the shared resource to prevent other threads from accessing it.
Unlock the mutex after finishing the operation on the shared resource to allow other threads to access it.
Example: pthread_mutex_t mutex; pthread...
