What is a colligative property? O A property that depends on the number of particles in solution, but not on the nature of the particles. O A property that relates the temperature of a gas to the pressure of the gas. O A property that depends on the specific chemical behavior of the constituent elements and not on the amount in solution. O A property that can only be measured when the moles of gas are constant. O A property that enhances the solubility of a molecule in water.
