Water at room temperature is placed inside and the vacuum pump is then used to evacuate the vessel. When the air pressure is reduced to the vapour pressure of water at room temperature the water will begin to boil.

When the vacuum is turned on the pressure exerted on the balloon decreases and the balloon can expand until the bell jar is completely filled. When the air is allowed back in the jar, the pressure is reestablished and the balloon returns to...

The chemicals are arranged such that there are many pockets of air trapped inside the shaving cream. The air pockets in shaving cream will expand in a vacuum. As the pressure gradually decreases the v...

Great science fair experiment. 1. Find a FLASK (Something that won't crank due to pressure) 2. Boil water and add it to the flask 3. seal it and invert the FLASK 4. place an ice cube or two on top. 5. the condensing of the gas abov...
