in this video we are covering MCQ of thermodynamics with tricks.
here we are covering RPSC college proffesor chemistry syllabus.
All the questions are from previous year question paper of RPSC, NEET, SET,GPSC, CSIR NET EXAM.
this video will helpful for all the compation exams like CSIR NET, pgt chemistry, bhu chemistry, du entrance, phd entrance, NEET, IIT JAM, MH- SET, GSET and other exams.
Thermodynamics is a field of science that deals with the quantitative relationships between energy sources, and the study of heat and work interconversion. There are four rules of thermodynamics, and these are: zero law states that if two systems are in thermal equilibrium with a third system, then the first two systems are in thermal equilibrium. The first law states that, the total energy of an isolated system remains constant, it is a law of conservation of energy. The energy can neither be created nor destroyed, it can only be transferred from one form to another. The second law of thermodynamics states that, over time, the entropy of an isolated system that is not in equilibrium must rise and achieve the ultimate equilibrium value. Third law of thermodynamics states that the entropy of a system becomes constant as the temperature approaches absolute zero. The viability of a given transformation is determined by thermodynamics.
A thermodynamic process where no heat is exchanged with the surroundings is
- isothermal
- adiabatic
- isobaric
- isotropic
Answer: (b)
