Why do particles in liquid water at 0° C have more energy as compared to particles in ice at the same temperature?

Why do particles in liquid water at 0° C have more energy as compared to particles in ice at the same temperature? Correct Answer Because the particles in ice absorb heat energy during the process of conversion from ice to liquid water.

The correct answer is Because the particles in ice absorb heat energy during the process of conversion from ice to liquid water.

 Important Points

  • At 0 °C Water has already absorbed the latent heat of fusion, ice at the same temperature has not absorbed the latent heat of fusion and has less kinetic energy.
  • The molecules of water have more energy than the molecules of ice at the same temperature, this is because as ice is melted to the liquid state, ice absorbed energy which is used in breaking the inter particles forces between the ice, and hence water molecules has more kinetic energy.

​

Additional Information

  • Latent heat of fusion is the enthalpy change of any amount of substance when it melts.
    • The Latent heat of fusion is the amount of heat required to change 1g of a substance at the temperature of its melting point from the solid to the liquid state without changing temperature. 
  • Kinetic energy is defined as the motion of particles or movement of any substance or motion possessed by a body.

Two refrigerators M and N operate in series. The refrigerator M absorbs energy at the rate of 1 kW from a body at temperature 400 K and rejects energy as heat to a body at a temperature T. The refrigerator N absorbs the same quantity of energy which is rejected by the refrigerator N from the body at temperature T, and rejects energy as heat to a body at temperature 800 K. If both the refrigerators have the same C.O.P., what is the value temperature T?
