Ice at 0^(@)C enclosed in an adiabatic shell and is compressed to a pressure of 600 atm. It is known that an increase in the pressure of 138 atm causes the melting point of ice to drop by 1 K. Assuming the phase diagram in this part to be linear, find the fraction of the ice that is going to melt.

The following observations were recorded on a platinum resistance thermometer: Resistance at melting point of ice = 3.70 ohm, resistance of boiling point of water at normal pressure Omega and resistance at t”^(@) C = 5.29 ohm. Calculate (i) Temperature coefficient of resistance of platinum, (ii) Value of temperature t

    `H_(2)O` molecules are more closely packed in solid state
    B
    ice crystals have hollow hexagonal arrangement of `H_(2)O` molecules.
    C
    on melting of ice the `H_(2)O` molecules shrinks in size
    D
    ice froms mostly heavy water on first melting.

    (i) Calculate the change in entropy for the fusion of 1 mole of ice. The melting point of ice is 273 K and molar enthalpy of fusion for ice = 6.0 kJ/mole. (ii) Calculate the standard of entropy change for the following reaction. {:(,H^(+)(aq), + OH(aq)to, H_(2)O(l)),(S^(@)(298 K)//JK^(-1)mol^(-1),0,-10.7,+70):}

    As its melting point, ice is lighter than water because:

    At its melting point ice is lighter than water because

    At its melting point ice is lighter than water because

    Assertion: The melting point of solid (except ice) increases with increase in pressure. Reason: An increasion in pressure favours the change where volume decreases.
