What is the change in entropy when 1gram of ice at 0° C is converted into water at the same temperature?
My attempt at the solution.
dS = dQ/T, where S is entropy, Q is heat energy and T is absolute temperature.
Again Q = mass X specific heat capacity X Change in temperature(ΔT)
T in the denominator is absolute temperature so 0+273 = 273K.
mass = 1 gm. I don't know what to substitute for sp.heat capacity? Whether sp.heat of water or sp.heat of ice? Again for ΔT, what values to substitute? Revered members can help.
