The purpose of a gas meter is to monitor how much gas a particular house is using. Customers are then billed according to how much gas they have used from the meter.
That depends what you want to measure about the gas: its volume, mass, transparency, temperature, etc. The really isn't such a thing as a "unit of measurement of gas", there are units of measurement for mass, volume, temperature, etc., all of which can be attributes of a specific gas.
Because all the gas could come out
You multiply the volume of the gas by its density. The volume will depend on the specific gas, and on the pressure and temperature of the gas. As an example, a cubic meter of air has a mass of approximately 1.2 kg/m3. For other gases, the numbers may be quite different.
the answer of the joke
Prisoners were told the gas chambers were showers.
Hitler decided to gas the Jews in nazi Germany
The nazi's did not use poison gas that was the German Republic or Weimar Republic during world war one nazi's were a political "group" [party] made by peopl who for all we know they could've been best friends with himlar nazi's were behind world war two
They stopped using chambers in 1945 when the Nazi's came out of power and were wanted for genocide
The main way of exterminating the Jews was gassing. The jews were driven into gas chambers like cattle and then gassed. Others had to work for the nazis and succumbed to the harsh conditions in the camps. Many were shot by nazi guards, too.
The gas vans were moveable gas chambers which were used in most of the death camps, they were adapted from the T-4 programme.
they took the Jews to the death camp and took them to the gas chambers and the gas killed them all
they was put in a room of gas then they died
Those in charge of the cruelty and death that were being enacted in the camps. Often times, however, the Nazi guards would round up all the prisoners and force them on death marches, which would always end with the guards forcing the prisoners into a body of water and machine-gunning them.
The reason they wore gas masks is because they weren't sure weather the Nazi's would drop gas bombs as they did in WW1
there were various sizes, the largest having a capacity of 2000.
The gas chambers were dressed up to look like showers. This served many purposes: it meant that the victims would undress themselves. The first gassings took place with the victims fully clothed and it was found that it was harder and time consuming to undress the corpses, as the workers had to search for hidden valuables. The Jews were also told that they had to wash and be de-loused after their journeys to the camps, before they could join the general population (this was what actually happened to those who did join the general population). This made the victims more compliant and the illusion of normality and changing rooms and showers helped keep many calm. The drainage of the shower rooms also helped with the cleaning of the gas chambers after it had been cleared of victims.
