Thermodynamics

  • Thermal equilibrium: 

    • State of a system is an equilibrium state if the macroscopic variables that characterise the system do not change. 
    • Two systems at the same temperature are said to be in thermal equilibrium with each other.

 

  • Adiabatic wall: Insulating wall that does not allow the flow of energy through it

 

  • Diathermic wall: Conducting wall that allows the flow of energy through it

 

  • Zeroth law of thermodynamics : If two bodies A and B are in thermal equilibrium and A and C are also in thermal equilibrium then B and C are also in thermal equilibrium.

 

Heat

  • It is a form of energy.
  • The flow of heat between two bodies stops when their temperatures equalis…
