Explain Modes of Energy Transfer Modes of energy transfer refer to the various mechanisms by which energy can be exchanged between different systems or within a system. In the context of thermodynamics, there are three primary modes of energy transfer: conduction, convection, and radiation. These modes of energy transfer are often encountered simultaneously in real-world …
What is Absolute Temperature? Absolute temperature refers to temperature measured on the Kelvin scale, denoted by the unit “kelvin” and symbolized as “K.” The Kelvin scale is an absolute temperature scale, which means it starts from absolute zero, the lowest possible temperature at which particles have minimal kinetic energy. Key points about absolute temperature The …

What is Pressure? Pressure: Pressure is a fundamental thermodynamic property that characterizes the force exerted per unit area. In thermodynamics, pressure plays a crucial role in describing the state of a system, particularly in gases and fluids. It is defined mathematically as the force applied perpendicular to the surface of an object divided by the …

What is the Quasi-Static process? A quasi-static process, also known as a quasi-equilibrium process, is an idealized concept in thermodynamics used to analyze and model the behavior of systems undergoing changes. In a quasi-static process, the system undergoes a series of infinitesimally small and reversible steps, allowing it to be in equilibrium at every stage …
In thermodynamics, several key concepts are used to describe the behavior and transformations of a system. Here are the definitions of the terms state, path, process, and cycle: In summary, the state of a system is defined by its properties, a path describes the sequence of states during a process, a process involves changes in …

What is Thermodynamic Equilibrium? Thermodynamic equilibrium is a fundamental concept in thermodynamics, describing a state in which a system has reached a condition of balance where no further changes or tendencies to change occur within the system. In other words, it is a state of stability characterized by the absence of any macroscopic driving forces …

Introduction Thermodynamics is the branch of physics that deals with the study of energy and its transformations within a system. It provides a framework for understanding the behavior of matter and energy, particularly in relation to heat and work. The laws of thermodynamics govern the fundamental principles that dictate the direction and efficiency of energy …

The main difference between enthalpy and entropy is that enthalpy is a measure of the total energy of a system that includes the effects of pressure and volume, while entropy is a measure of the disorder or randomness of a system.
Enthalpy and internal energy are two fundamental concepts in thermodynamics that describe the energy of a system. Both are related to the heat and work done on or by a system, but they are not the same thing.
Difference Between Gas Turbine and Steam Turbines What is a Gas Turbine? A gas turbine generates rotational motion from a heat differential, which in this case is caused by combustion. What is a Steam Turbine? Steam turbines use a steam mixture to turn a shaft to produce the desired rotary motion. The primary similarity between …
