what substances affects the boiling point of water?

Answer 1

Just about anything that dissolves into water will impact its boiling and freezing point. Any type of salt is very effective.

Answer 2

Atmospheric pressure influences the boiling point of water. When atmospheric pressure increases, the boiling point becomes higher, and when atmospheric pressure decreases (as it does when elevation increases), the boiling point becomes lower.

Pressure on the surface of water tends to keep the water molecules contained. As pressure increases, water molecules need additional heat to gain the speed necessary for escape. Pressure cookers work on this principle. When a pressure cooker gauge shows 100 pounds pressure per square inch, the temperature inside the cooker is more than 300° F (149° C).

Lowering the pressure lowers the boiling point because the molecules need less speed to escape. The low atmospheric pressure on high mountains lowers the boiling point to such an extent that water cannot get hot enough to boil eggs satisfactorily.

Did that help?

Answer 3

Almost all substances will raise the boiling point of water. Pure water boils at 100C or 212F. As you add different substances such as salt or antifreeze (to name just two) the boiling point will rise above 100C.

Answer 4

Purnellsweet, has it right. Salt is part of the equation, the primary reason,though , minus any additions to the water, is air pressure.The lower the air-pressure,the higher the boiling point. If you ever get to, Denver Colo., it takes forever to boil water for tea ...

Answer 5

Salt

Back in the 1800s a canner discovered that you could add salt to water and it raised the boiling temperature

This meant he could cook his food that needed to be canned more quickly than his competitors and crank out more volume of stuff....he quickly patented the idea

Answer 6

1.) Altitude

2.) Impurities within the water such as salt

3.) Atmospheric Pressure

Answer 7

Salt. That's always a winner.
