Best Answer

vacuum is a volume of space that is essentially empty of matter, such that its gaseous pressure is much less than atmospheric pressure. The word comes from the Latin term for "empty".

Now, u tell me if u measure it by BAR or temp?

Though T is directly proportionate to P, measurement of pressure with temperature in a vacuum cleaner is an absurdist theory.

Why few substances are dried only by vacuum dryer?

A Vacuum drier dries things without heat. As the pressure drops, the boiling point of water (or any other liquid, for that matter) drops. If you get the pressure low enough, water will boil at room temperature. If the substance that you are drying is damaged by temperature, for instance, by a chemical reaction that occurs if it gets hot, then you have to dry it at a low pressure. That is what a vacuum dryer does.

How does quartz work in the temperature sensor inside the vial in freeze dryer?

A quartz temperature sensor inside a vial in a freeze dryer works by measuring the frequency of the quartz crystal. The quartz crystal is designed to vibrate at a specific frequency when it is exposed to a certain temperature. As the temperature inside the vial changes, the frequency of the quartz crystal changes as well. The frequency is then measured by the temperature sensor and compared to a reference temperature, allowing the freeze dryer to accurately measure and control the temperature of the vial.


What happens to a liquid-vapor system at equilibrium if the temperature decreases?

If the temperature of a liquid decreases, so does the vapor pressure. Clothes dry faster in a warm or hot clothes dryer than they do when hung up in a cool house. The vapor pressure of water is higher when it is warmer in the clothes dryer. Clothes dry faster in the sunshine than in the shade. Sunshine is warmer.


Where is the ac vacuum check valve on a 2002 Jeep Wrangler?

Low pressure test ports are near the receiver/dryer on most vehicles. If you can't find it near the firewall, check between the receiver/dryer and the compressor. A few vehicles don't have a low pressure test port. In that case, the system is tested by pulling the low pressure sensor, jumping it and connecting the gauges directly to the receiver/dryer. But check the entire length of the low pressure line before you do that.

What did Alexander godefoy do for your society?

Alexander Godefoy invented hair dryer. The hair dryer came from a vacuum, connecting the exhaust from the vacuum to a hose. Later he improved the vacuum model and created the first electric hair dryer. It looked (and was) like a whole bunch of tuba tubes that blew air into your face and your hair to dry it. This early model was later improved by Chinese scientists into the modern hair dryer we have now.
