Question

Problem 21

Answer 1

Given information

We are given that:-

Room temperature .

Step-by-step explanation

Step 1.

Yes, water can be boiled without heating. This is done by increasing the pressure on the surface of water inside a closed insulated vessel. By doing so, the boiling point of water can be decreased to room temperature.

 

Everyone knows that the boiling point of water is . What if you can boil water at much less than . The answer lies in the application of atmospheric pressure and vapor pressure. Now, boiling temperature is a temperature when the vapor pressure of a liquid becomes equal to the atmospheric pressure.

 

A woodstove or fireplace can be a lifesaver during a power outage, and not only as a general source of heat. You can also boil water as you would over a campfire, with the pot placed atop a woodstove, or via the built-in water reservoirs some models include.
