Why partially evacuated chamber is used in aneroid barometre?
A partially evacuated chamber is used in an aneroid barometer because changes in atmospheric pressure will cause the flexible chamber to expand or contract, which is then measured and indicated on the barometer dial. This mechanism allows the aneroid barometer to measure variations in air pressure without the need for a liquid-filled chamber like in a traditional mercury barometer.
Why did Rutherford do the gold foil experiment in a evacuated chamber?
Rutherford conducted the gold foil experiment in an evacuated chamber to reduce interference from air molecules that could affect the path of alpha particles. This ensured a clean environment for the experiment and allowed for more accurate measurements of the scattering of alpha particles by the gold foil, leading to the discovery of the atomic nucleus.
What is an experiment to demonstrate that sound requires a medium to travel?
One experiment is to use a bell inside a vacuum chamber. When the chamber is evacuated of air, the sound of the bell will not be heard because there is no medium (air) for the sound waves to travel through. This demonstrates that sound requires a medium to propagate.
How do you use a pycnometer?
Take G-DenPyc 2900 as an example: step 1. weight sample mass; step 2. put sample into sample chamber; step 3. cover sample chamber and switch gas on; step 4. input sample mass into analyzer software and click "start" to operation; step 5. about 5 mins to wait sample results.
How do you detect leak in a vacuum chamber?
The simplest method would be to mount a pressure gauge onto the chamber, then to observe whether the reading changes. It should remain at "zero" indicated gauge pressure. If your instrumentation is relative to atmospheric pressure, it would be a "minus" pressure and would vary with local atmospheric pressure. For very accurate readings, you would need something more sophisticated, such as an ionisation gauge.
What is an evacuated chamber?
It is a chamber that consits of no particles and its inside, therefore, is a vaccum. (Get it? Evacuated > Vaccum).The volume inside of an evacuated chamber is zero and is used so an experiment conducted inside of it has little risk of being effected by particles. So in Rutherford's experiment, they use it so no gas particles/atoms/nuclei can get in the way of the alpha radiation which gets absorbed by the air after 5cm of travel and has such a large size and mass so the experiment has big chance of being affected by air particles.Hope this helps :),x BBC Merlin Fan
What is a beampipe?
A beampipe is the evacuated chamber through which a beam of particles is accelerated in a particle accelerator.

What is a sentence with the word evacuated?
During World War II, many London children were evacuated to the countryside. When a storm came the town had to be evacuated. To create a low pressure chamber, the air is evacuated from a sturdy container.
How were most Jews killed in Auschwitz?
Gas chamber and Mass shootings
What was the purpose of a gas chamber?
To execute mass killings of humans quickly.
Why were children evacuated and where were they evacuated to?
Children were evacuated for their safety because of the bombings near their home, they would usually be evacuated to the countryside.
Propose a way to determine the density of air?
Get a vacuum chamber. Get all the air out of it, and weight it. This is the true weight of just the vacuum chamber. Fill it with air, and then weight it again. Subtract the new weight from the initial weight to get the mass of the air contained within the chamber. Find the volume of the chamber as well. density= mass/ voume. Hope it heelpss(:
Why didn't woman get evacuated?
Evacuated from where?
How did the Nazis mass-murdered people during the Holocaust?
The two most common ways they used to mass kill them were by mass shootings and the gas chamber.
What is the definition of evacuated?
Evacuated means 'removed from' .
What is effusions?
effusion is the process where individual molecules flow through a hole without collisions between molecules. effusion is the process where the gas molecules are passed through a small opening to an evacuated chamber
