Can water boil at room temperature or is it impossible?

Answer 1

The 2 persons above me are correct. Water can boil at room temperature. Boiling point is defined as the temperature at which the vapor pressure becomes equal to atmospheric pressure. If atmospheric pressure is high, then it will take more heat to get the vapor pressure equal to atmospheric pressure. Conversely, by lowering atmospheric pressure the boiling temperature can be lowered. So, by placing water in a good vacuum compartment, it can be made to boil at room temperature itself.

Answer 2

Water Boiling At Room Temperature

Answer 3

Do this thought experiment: Boil the kettle, and then place it in a deep-freezer. On its way from boiling to sub-zero, the temperature function is continuous. Therefore, the temperature *must* reach room temperature at some point on the way down after boiling. By basic thermodynamics, if the boiled kettle is placed in a room temperature environment that is sufficiently large and open, it will reach equilibrium at room temperature. Where this gets tricky is when the room is small and closed, and the heat from the kettle re-sets the room temperature to an equilibrium temperature that is higher than the original temperature. Nevertheless, the ultimate equilibrium temperature will be exactly equal to the "new" room temperature.

Answer 5

The other person is right. You can boil water at ambient temperatures if you adjust the internal pressure inside the flask that holds the water. In chemistry class they show you how to do it with a flask with two openings and with a buchner funnel you can filtrate. But I think you change the pressure by attaching the pressure side of a running water outlet to the special opening in the flask and cap the top. The water will start to boil at room temp. Can someone out there correct me on the set up.

Answer 6

At 1 atmosphere of pressure, water boils at 100 degrees celsius. If you placed a pan of water in an enclosure and were capable of reducing the pressure inside the enclosure enough, you could get water to change state (boil) at room temperature.

Answer 7

You can boil water at room temperature by decreasing the air pressure

Answer 8

Yes. Of course you can boil water at room temperature. It looks like the geniuses at Answers are at it again with their assumptions. If the air pressure is reduced the boiling point tempersture will reduce. If a jar of water is placed in a vacuum the resulting drop in the ambient pressure will reduce the boiling point. Also, as the pressure of the ambient is increased, the boiling point will increase. I have boiled water at 72 degrees F. many times. Ask your science teacher.

Answer 9

It all depends on the altitude u are at. I lived at Quito Ecuador at an altitude of 9200 ft. U could boil red beans in an open pan for a week and they would not be near done.

Answer 10

It is totally possible if air pressure is reduced enough.
