Mindblown: a blog about philosophy.

The second law of thermodynamics states that any spontaneously occurring process will always lead to an escalation in the entropy (S) of the universe. In simple words, the law explains that an isolated system’s entropy will never decrease over time. Nonetheless, in some cases, where the system is in thermodynamic equilibrium or going through a reversible process,…

The first law of thermodynamics uses the principles of energy conservation. It establishes a relationship between the internal energy of a system, heat transfer, and work done. According to the first law, the change in internal energy equals the heat supplied to the system minus the work done by the system [1-4]. The conservation of energy…

The Zeroth law of thermodynamics states that if two bodies are individually in equilibrium with a separate third body, then the first two bodies are also in thermal equilibrium with each other. This means that if system A is in thermal equilibrium with system C and system B is also in equilibrium with system C,…

Thermodynamics laws define the fundamental physical quantities like energy, temperature and entropy that characterize thermodynamic systems at thermal equilibrium. These thermodynamics laws represent how these quantities behave under various circumstances. How many laws of thermodynamics are there? There are four laws of thermodynamics and are given below:

Thermodynamic properties are defined as characteristic features of a system, capable of specifying the system’s state. Thermodynamic properties may be extensive or intensive. What is Enthalpy? Enthalpy is the measurement of energy in a thermodynamic system. The quantity of enthalpy equals the total heat content of a system, equivalent to the system’s internal energy plus the product of…

A system undergoes a thermodynamic process when there is some energetic change within the system that is associated with changes in pressure, volume and internal energy. There are four types of thermodynamic processes that have their unique properties, and they are: A thermodynamic cycle is a process or a combination of processes conducted such that…

Thermodynamics has its own unique vocabulary associated with it. A good understanding of the basic concepts forms a sound understanding of various topics discussed in thermodynamics preventing possible misunderstandings. Thermodynamic Systems System A thermodynamic system is a specific portion of matter with a definite boundary on which our attention is focused. The system boundary may…

Thermodynamics is classified into the following four branches: Classical Thermodynamics In classical thermodynamics, the behaviour of matter is analysed with a macroscopic approach. Units such as temperature and pressure are taken into consideration, which helps the individuals calculate other properties and predict the characteristics of the matter undergoing the process. Statistical Thermodynamics In statistical thermodynamics,…

The distinction between mechanics and thermodynamics is worth noting. In mechanics, we solely concentrate on the motion of particles or bodies under the action of forces and torques. On the other hand, thermodynamics is not concerned with the motion of the system as a whole. It is only concerned with the internal macroscopic state of…

Thermodynamics in physics is a branch that deals with heat, work and temperature, and their relation to energy, radiation and physical properties of matter. To be specific, it explains how thermal energy is converted to or from other forms of energy and how matter is affected by this process. Thermal energy is the energy that…
