Find the increase in entropy of 1.00 kg of ice that is originally at 0°C and melts to form water at 0°C.

option(1)

CONCEPT:

• Entropy is a property of thermodynamics that is associate with the state of disorder, randomness, or uncertainty

Entropy is given by:

  (ΔQ is change in entropy by a change in temperature)

EXPLANATION:

Here, Q is the heat necessary to melt 1.00 kg of ice and is given by

( m is mass and L_f is the latent heat of fusion) 

Latent heat of fusion of water is (334 kJ/kg)

hence we know that  on putting the value we get 

 = 1.22 × 10³ JK^-1

Additional Information

• Latent Heat of Fusion is the amount of heat required to change 1 g of a substance at the temperature of its melting point from the solid to the liquid state without changing temperature. 
  • ​Latent heat of fusion of water is taken as (334 kJ/kg)
