Solutions having the same osmotic pressure are called:
A liquid is in equilibrium with its vapour in a sealed container at a fixed temperature. The volume of the container is suddenly increased.
  1. What is the initial effect of the change on vapour pressure?
  2. How do rates of evaporation and condensation change initially?
  3. What happens when equilibrium is restored finally and what will be the final vapour pressure?
