Plz explain this question.. n in column li column (a) freezing of water at 273 kand 1 atm (b) expansion of 1

Match the thermodynamic processes given under Column I with th0 from 300 K to 600 K, followed by reversi- ble cooling to 300 Kat 1 atm (t) AG=0

    check this it helps😊🙏

    one by one I will discuss each part

    so sir in first . in ..freezing of water there is change in heat what about work done and internal enegy

    eduncle-logo-app

    freezing of water in equilibrium so del G=0, entropy negative u know

    eduncle-logo-app

    work done is not eaual to zero..as expands on freezing

    eduncle-logo-app

    got shweta

    eduncle-logo-app

    please accept the answer if you got it😊🙏

    sir water expands on freezing how

    eduncle-logo-app

    When frozen, water molecules take a more defined shape and arrange themselves in six-sided crystalline structures. The crystalline arrangement is less dense than that of the molecules in liquid form which makes the ice less dense than the liquid water. ... Thus water expands as it freezes

    mainly shweta i explains the case what happen here...

    eduncle-logo-app

    here volume changes due to phase changes...and temp is constant so internal energy is constant and process is isobaric..so work is done here
