What physical effect can change the boiling point of a substance?
pressure can affect the boiling pressure of a substance
as when pressure increases the particles are closer together and so require more energy to boil therefore increasing the substances boiling pointÂ
hope that helps
The boiling point of a substance is dependent to the pressure. The pressure and saturated temperature are often presented in tables and sometimes in graphs. In addition, the amount of solute in the solution can also change the boiling point of the solvent.
