One day, Cameron decided to see if this was really true (he didn't believe it). He added some salt to a beaker of water and used an accurate thermometer to measure the temperature at which the water boiled. He found that the boiling point was raised to 101.4C. He had measured the boiling point of pure water earlier and found it to be 99.7C by his thermometer. How manyC did the boiling point increase in his experiment?
