What is the effect of pressure on melting and boiling point of a substance?

Expert Answer:

As the vapour pressure increases, boiling point decreases because boiling point is the temperature at which temperature of the liquid becomes equal to the atmospheric pressure.

On increasing the pressure, temperature will increase and hence melting of a substance takes place with a faster rate that is melting point decreases.
