entropy is the amount of randomness or disorderness in a body.......when ice melts to water entropy increases as the molecules in water are more free to move than in ice....so randomness increases .......thus entropy also increases.......

please mark my answer as brainliest

Final answer:

Entropy is a thermodynamic state quantity that measure the disorder or randomness of molecules in the system. Entropy increases in the case of ice melts to liquid water.

Given that: We are given the term Entropy and the system ice melt to liquid water.

To find: We have to find what entropy is and what happens to entropy when ice melts to liquid water.

Explanation:

  • Entropy is a thermodynamic state quantity that measure the disorder or randomness of molecules in the system. Greater the disorder or randomness, greater is the entropy and vice versa. It is denoted by the letter S.
  • Entropy is a state function. It is an extensive property.
  • Change in entropy ΔS for a finite change of system at constant temperature is given by

    ΔS =  \frac{qrev }{T}  where T = Temperature,  qrev= heat absorbed reversibly

  • ΔS has units JK⁻¹, which is referred to as entropy unit (e.u).
  • Entropy increases in the case of ice melt to form liquid water. In ice, water molecules are more tightly bound to each other. The vibration of molecule held in ice slow and they have very little freedom of movement that means very little disorder hence very low entropy. When heat coming ice melts to liquid water. As the temperature increases the vibration of molecule increases so molecules are free to move everywhere in water. That means increase the disorder or randomness hence increase the entropy.
