Some desalination processes are based on evaporating seawater. Energy can be saved by reducing the boiling temperature of the water. From Fig. 1.13, determine the boiling temperature of the water if the pressure is lowered to 0.5 atm.

Suppose we approximate the tiny tubes carrying water up to the branches of a tall tree by a simple tube of diameter 0.005 mm. Taking the values for σ = 0.073 N/m and θ = 15◦, calculate how high the water can rise in such a tube.
