What is solution
Homogeneous mix of 2/more pure substance
System
A region or a space that contains matter and energy
Write the condition for spontaneity of reaction with respect to entropy
What is thermodynamics
Study of relation between heat word temperate and energy
Surrounding in thermodynamics mean
Everything outside the system is called surrounding
Open system
Exchange of both matter and energy
Close system
Only energy exchanges
Isolated system
Neither energy nor matter exchanges
Extensive property
Depend on amount of meta present in it
Eg - mass volume
Intensive property
Doesn't depend on amount of matter present in it
Example boiling point melting point etc
State function
Property with depends on it safe a function and independent of path followed to attain it
Thermodynamics equilibrium
State function that doesn't change with time
Isotheral process
Temperature is constant
Isobaric process
Pressure is constant
Isochoric process
Volume is constant
Abiatic process
Neither observe heat form surrounding nor relies heat
Reversible process
A process which is reversed without leaving a trace on system or surrounding
Nature of work
W= F x D
Nature of work is defined as force into displacement
First of thermodynamics
