Essays on Thermodynamics

Magnesium is one of the well-known and promising materials for lightweight applications due to its high specific strength and low density. They are commonly prepared through casting and thus their casting properties are important for their actual applications. Regrettably, Mg alloys are prone to hot...

Out of all the important concepts of science in the life of human beings, thermodynamics ranks the highest. It is through this invention that so many appliances have been made to make the life easy and comfortable. The idea of thermodynamics traces its origin to...

The following claim “What are the processes that drive Earth towards non-equilibrium,” can be deconstructed into two key elements: How did Earth’s thermodynamic system evolve away from thermal equilibrium? And what processes drive it towards non-equilibrium? The present-day Earth system is notably unique when contrasted...

Science and engineering to a large extent live in separate worlds with their own journals and conferences. It therefore took several years for thermodynamics to enter engineering circles. Well, in this article, ‘Current Trends in Finite-Time Thermodynamics,’ the author, Bjarne Andresen (a Professor of Physics...

We have all studied physics in our school days. While some of us have moved to other fields but we do come across these terms in our daily life. For example, we experience force when we are travelling in a vehicle in the morning when...

Abstract Jiang Zhengwu Et al. reported a paper on increased strength and various mechanisms for mortars at cryogenic temperature. In this paper, the strength of mortar at cryogenic temperatures was experimentally studied and empirical model was prepared. The relationship between the increased cryogenic strength and...

A physical change is a change in which the composition of the substance remains unaltered and no new substances are produced. A change of state is still a physical change, as water freezing into ice is still water in a different form. A physical change...
