Question
Will entropy increase or decrease in the following changes?
  1. Sugar dissolved in water.
  2. Normal egg to hard boiled egg.
✓

Answer

  1. When sugar dissolves in water, entropy increases because molecules of sugar become free to move disorder increases.
  2. Hard boiled egg has more entropy because denatured protein has random coil structure having more disorder where as normal egg have ordered structure of protein.
