Specific Heat Formula is S=Q/mdT
For adiabatic process There will be no transfer of heat or matter therefore y first law of thermodynamics dQ = dU + dW
dQ = 0 for adiabatic..
therefore S= 0

What do you mean by triple point of water? Why is it unique?

Posted by Anirudha Patil 7 years ago

CBSE > Class 11 > Physics

1 answers

Gaurav Seth 7 years ago

It is the temperature at which the three phases of water, namely, ice, liquid water and water vapour are equally stable and coexistent. The triple point is suitable because it is unique, i.e., it occurs at one single temperature = 273.15 K and one single pressure of about 0.46 cm of the Hg column. This point is unique because any temperature or pressure higher or lower will change the phase of one or more states of water.
