Explain and define the 3 laws of thermodynamics

Answer» Zeroth Law of Thermodynamics\tZeroth law of thermodynamics states that when two systems are in thermal equilibrium through a third system separately then they are in thermal equilibrium with each other also.\tForeg: - Consider two systems A and B which are separated by an adiabatic wall. Heat flow happens between systems A and C, and between B and C, due to which all 3 systems attain thermal equilibrium.\t\tFirst Law of Thermodynamics\tThe First law of thermodynamics is same as law of conservation of energy.\tAccording to law of energy conservation: - Energy can neither be created nor be destroyed, only transformed to other forms.\tAccording to first law of thermodynamics:- The change in the internal energy of a closed system is equal to the amount of heat supplied to the system, minus the amount of work done by the system on its surroundings.\tExamples:-\xa0Consider a ball falling from the roof of the building when at top of the building the ball has only potential energy and when it starts falling potential energy decreases and kinetic energy starts increasing. At the ground it has only kinetic energy.Second law of ThermodynamicsThere are 2 statements of second law of thermodynamics given by two scientists:\tKelvin-Planck ∫Statement: - No process is possible whose result is the absorption of heat from a reservoir and the complete conversion of the heat into work.\tClausius statement: - No process is possible whose result is the transfer of heat from a colder object to a hotter object.Explanation of Kelvin-Planck Statement: It is always impossible that the total amount of heat which is supplied to system will get converted to work, and there will always be loss of heat. Complete conversion of heat into work is not possible.Explanation of Clausius statement: - Transfer of heat from colder body to hotter body won’t take place until some external work is done on the system.

Define redox reaction?

Answer» The reaction in which reduction and oxidation occurs simultaneously are called redox reaction<br>The reaction which consist of both oxidation and reduction is known as redox reaction. Hear red means reduction and ox means oxidation, so combination of reduction and oxidation is called redox reaction.<br>It is the chemical reaction in which both increase and decrease in oxidation state or number take place.<br>It is a combination of reduction and oxidationRedox = reduction and oxidation<br>There are two types of Redox reactions\tDirect Redox reaction\tIndirect Redox reactionDirect Redox reaction: In which oxidation and reduction both occur in same beaker. In this electron so produced does not travel to large distance.For example: A beaker containing Zinc rod dipped in Copper sulphate solution in this the following reaction occur:Zn + CuSO4 --> ZnSO4 + CuZinc CopperSulphate Zinc Sulphate CopperIn this zinc being more reactive displaces copper from copper sulphate and forms zinc sulphate and copper.Indirect Redox reactions: In it oxidation and reduction occur in different beakers. The electron so produced has to travel a certain distance that leads to generation of current.Example: Daniel cell: A cell containing Zn-Cu couple that we are going to study in detail now as given below but before that let us make you familiar with the general term used in redox reaction that is Redox couple.<br>Reaction in which oxidation and reduction takes place simultaneously
