Difference between first law of thermodynamics and second law of thermadynamics? |
| Answer» Basic idea:First law:\xa0First law of thermodynamics is a\xa0version of the law of conservation of energy.Second law:\xa0Second law of thermodynamics states\xa0what types of thermodynamic processes are forbidden in nature.Content:First law: First law of thermodynamics states that energy can be neither created nor destroyed.Second law:\xa0It is impossible to construct a perfect heat engine or a perfect refrigerator. It is impossible to construct a perpetual motion machine. It is impossible to completely convert heat into work. Heat doesn’t spontaneously flow from a cold reservoir to a hot reservoir. The entropy of an isolated system never decreases.Uses:First law:\xa0The equation; ΔU= ΔQ+ ΔW can be used to calculate the algebraic value of one quantity if other two quantities of the equation are known.Second law:\xa0The second law can be used to calculate the maximum achievable thermal efficiency (Carnot efficiency) of a given heat engine. | |
