Enthalpy is the heat content of a system, while entropy is the measure of disorder or randomness in a system.

• Enthalpy is the sum of internal energy and the product of pressure and volume.

• Entropy is the measure of the number of ways energy can be distributed in a system.

• Heat loss in entropy occurs due to the transfer of energy from a hot object to a cold object.

• Entropy always increases in a closed system, leading to a decrease in available energy.

• Enthalpy and entropy are impor...read more

Adiabatic process is a thermodynamic process where no heat is exchanged with the surroundings. Hyperbolic process is a type of adiabatic process.

• Adiabatic process occurs when there is no heat transfer between the system and its surroundings

• Hyperbolic process is a type of adiabatic process where the pressure and volume of a gas are inversely proportional

• Adiabatic compression of a gas can cause an increase in temperature

• Adiabatic expansion of a gas can cause a decrease in tempe...read more

IDU and ODU are abbreviations used in air conditioning systems. IDU stands for Indoor Unit and ODU stands for Outdoor Unit.

• IDU is the unit that is installed inside the room or building, while ODU is installed outside.

• IDU is responsible for cooling or heating the air inside the room, while ODU is responsible for dissipating the heat outside.

• IDU is connected to ODU through refrigerant pipes and electrical cables.

• Examples of IDU include wall-mounted units, ceiling cassette units...read more

Diesel engines are commonly used in trains.

• Trains typically use diesel engines due to their high torque and fuel efficiency.

• Electric engines are also used in some trains, especially in urban areas.

• Steam engines were used in the past but are now rare.

• Hybrid engines that combine diesel and electric power are becoming more common.

• The type of engine used in a train depends on factors such as the distance it travels and the terrain it covers.

AC is a device that cools and dehumidifies air while cooler is a device that cools water or other liquids.

• AC is used to cool and dehumidify air in a room or building

• Cooler is used to cool water or other liquids for drinking or industrial purposes

• AC uses refrigerant to cool the air while cooler uses water or other liquids

• AC is more expensive and complex than cooler

• AC is more commonly used in residential and commercial buildings while cooler is more commonly used in industrial ...read more

Thermodynamics is the study of energy and its transformations in relation to heat and work.

• It deals with the behavior of energy and its conversion from one form to another.

• It involves the study of heat transfer, work, and the properties of substances.

• Thermodynamics is essential in designing and analyzing various mechanical systems.

• Examples include the study of engines, refrigeration systems, and power plants.
