Explanation:
Thermodynamics is a branch of physics that deals with the study of energy and its transformation, particularly in relation to macroscopic systems. Engineering thermodynamics is an application of thermodynamics to engineering systems and is concerned with the storage, transfer, and transformation of energy.
Statement 1: Thermodynamic properties are the macroscopic coordinates significant only for systems existing in states of thermodynamic equilibrium.
This statement is partially correct. Thermodynamic properties are macroscopic properties that describe the state of a system, such as temperature, pressure, and volume. These properties are significant only for systems existing in states of thermodynamic equilibrium. In a state of thermodynamic equilibrium, the system is in a stable state, with no net change in any of its properties over time.
Statement 2: Engineering thermodynamic studies about transfer and transformation of energy.
This statement is correct. Engineering thermodynamics studies the transfer and transformation of energy in engineering systems. This includes the analysis of heat transfer, work, and energy conversion processes.
Statement 3: Engineering thermodynamics studies about storage, transfer and transformation of energy.
This statement is also correct. Engineering thermodynamics is concerned with the storage, transfer, and transformation of energy. Energy storage can include the use of batteries, capacitors, and other energy storage devices. Energy transfer can include the use of pipes, ducts, and other conduits for the transfer of energy between different parts of a system. Energy transformation can include the conversion of energy from one form to another, such as the conversion of heat energy into mechanical energy in a steam turbine.
Therefore, the correct answer is option 'B' as both statement 1 and statement 3 are correct.
Consider the following statements:1. Thermodynamic properties are the ...
The second option is partially correct.That means engineering thermodynamics is a study of heat transfer, heat flow. But it is not a study of transformation of energy.
