Zeroth law of thermodynamic

1|Thermodynamics :which section of physics  dicuss the mutual conversion and relation of heat and mecanical power is called thermodynamics.

2|Heat :everything of the universe consist of two element .one is substance and another is power\energy.heat is a kind of power\energy.

3| tempreature :tempreature is a thermal condition of any substance.if it is amalgamate with another substance ,they will be thermal equilibration.this properties is tempreature.

4| zeroth law of thermodynamic:if the two substance is in thermal equilibrium with third substance then the first two substance will be in the thermal equilibrium with another.this is called zeroth law of thermodynamics.

5| the first law of thermodynamics : when the heat is taken by any system then some parts of heat spent to increase the internal energy or tempreature and remaining parts of heat are spent to complete the work.

6|internal energy:which energy stays   dormant condition in any system |or substance that can be occured  exponents at environment circumstance is called internal energy.

7|Isothermal change:in which change pressure and volume are changed but tempreature is fixed of any gas,this change

is called isothermal change.and the process of this is called isothermal process.

8|Adiabatic change : In which change any heat is not collected from outside or is not removed from gass even then pressure and volume are changed that change is called adiabatic change.

9|Isochoric process: In which process volume is consonat is called isochoric process.

10|Molar specific heat or molar heat capacity: To increase 1 degree of  1 mole gasses  tempreature which amount of heat is necessary is called molar specific heat or molar heat capacity.

11| second law of thermodynamics: Transalation of heat from any substance of lowest tempreature  to any substance of highest  tempreature  is not possible without  the help of any outside energy at any active device.
