This can be done by mixing different liquids of different boiling points together. For instance, if you mix ethyl alcohol and water, the liquid will boil at a boiling point somewhere in between about 78 degrees C for alcohol and 100 degrees C. for water. Chemistry books have charts listing different boiling points. Look up minimum boiling mixtures, or azeotropes in the index. Good luck!
