What is 1st law of thermodynamics??

Siddhi Shenoy 15th Jan, 2020

Hello Buddhu,

There are total three laws of thermodynamics: zeroth law, first law and second law.

The first law of thermodynamics statement is same as the statement for conservation of energy which says that energy can neither be created not destroyed. It can only be transformed from one form to

what books should i follow for semester preparation as well as for gate and other exams for thermodynamics strength of materials fluid mechanics? I am presently pursuing mechanical engineering

Manidipa Kundu Student Expert 13th Feb, 2020

hi,

for semester preparation you should follow the books suggested by you to your college faculty. see gate and semester exam is totally two different type exam, for understanding for basic conceptual part any good text book will be good. gate is numerical question type exam. you need to solve

this was a honable request why would automobiles are not eligible for SSC Je exams I observe the syllabus of mechanicals in SSC Je exams that topics are also related to automobiles like ic engine/ lubrication and thermodynamics properties etc.. a sincere request for give answer for this.. Thank you.

hi,

see ssc junior engineer has vacancy for diploma in mechanical, civil or electrical branch. you may find similarity and knowledge of mechanical syllabus, but you are not eligible to apply if you dont belongs to any of the similar branch or any combinational branch like, electrical and electronics engineer

what is mean by thermodynamics

Prashant Singh 10th Dec, 2019

We can define thermodynamics, as t he branch of Physics that deals with heat and temperature, and their relation to energy, work, radiation, and 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

thermodynamics mainly deals with

Apoorva Student Expert 9th Dec, 2019

Hello dear student,

Thermodynamics basically deals with the energy. the branch of physical science that deals with the relations between heat and other forms of energy (such as mechanical, electrical, or chemical energy), and, by extension, of the relationships between all forms of energy. . It also says that energy

Can pls anyone explain why in isothermal process dt is not 0?

Upendra Gupta 2nd Nov, 2019

Suppose we consider an Ideal gas. (Ah, one more definition, Ideal gas is a gas in which we neglect attraction between particles, therefore, no potential energy, thus here internal energy just refers to total kinetic energy) and make it undergo Isothermal process, then BY DEFINITION, temperature or Average kinetic energy

the formula of workdonein adiabatic process

Upendra Gupta 2nd Nov, 2019

Remember that the first law of thermodynamics states (Q+W+u^1)=(u^2)(Q+W+u^1)=(u^2)


Where u^u^ is internal energy.


By definition of an adiabatic process, the only way that internal energy can change is via work, which is defined as the integral of P dV


Before we can solve this integral, we need to formulate

2 moles of helium are mixed with n moles of hydrogen

Naufal Mohamed 9th Jan, 2020

No matter how many miles of helium is mixed with any number of moles of hydrogen there wont formation of any new compounds or molecules. Because helium is a noble gas. Which means it is in the most stable state possible. Hence you would still end up with two moles
