After sometime thermal flask get cooled..so how to we took it's an example of isolated syatem sir?

[@drgajapathyschemistryclass4773]

A good vacuum flask ( thermos flask) will not permit air to let in and get it cooled.

[@NirmalKumar-kt6mh]

@@drgajapathyschemistryclass4773 how long sir?

[@drgajapathyschemistryclass4773]

As long as it maintains it is an isolated system.Due to poor quality if it gets cooled it is no longer an isolated system. It then becomes a closed system.

@@drgajapathyschemistryclass4773 ok thank you sir

[@baskarank4120]

Sir in state equation why you change only ds why not dH

[@drgajapathyschemistryclass4773]

Equation of state should contain only the 4 observable variables P,V,T and composition To do so we are eliminating terms like G.S etc.
