Heat has randomising influence on a system and temperature is the measure of average chaotic motion of particles in the system. Write the mathematical relation which relates these three parameters.
उत्तर
Heat has randomising influence on a system and temperature is the measure of average chaotic motion of particles in the system. The mathematical relation which relates these three parameters is ΔS = `q_(rev)/ T`
Here, ΔS = change in entropy
qrcv = heat of reversible reaction
T = temperature
