The Bubble point of a liquid which has more than two components is the point at which the first vapor bubble id formed. The vapor which is formed is different in formation and composition that the liquid. For liquids which have only one component, the dew point and bubble point are the same and both together are referred to as the boiling point.

The Pour Point in case of a liquid refers to the lowest temperature at which the liquid will keep flowing. This point is used as estimation for determining up to what temperature a liquid or oil keeps flowing. If the temperature is decreased below the pour point the substance would stop flowing. This is true specially for lubricants.
