What gas are the Declaration of Independence and the US Constitution stored in?
They are kept in the inert gas argon with a slight humidity to keep the documents flexible.
Why is the declaration kept in helium?
The Declaration is actually kept in argon gas, not helium, with a little humidity to keep the document from becoming brittle. Argon gas is an inert gas and will not react chemically with any other chemicals in the ink or parchment of the document itself to harm it.
What kind of gas was used against the french colonial troops in 1915?
I'm guessing it was Mustard Gas. Later Phosgene was used. The Biological warfare in WW1 was relatively primitive, but nonetheless terrifying for all that, especially if all you had was a handkerchief to cover your face.......
What are the Advantages of tear gas?
Advantages of tear gas would have to be , it splits up large riot groups. Used by police.
What was the price of gas in Canada in 1985?
Gas prices in 1980 averaged about 86 cents per liter. This was a very high price to pay back then.
What gas are the Declaration of Independence and the US Constitution stored in?
They are kept in the inert gas argon with a slight humidity to keep the documents flexible.
What type of gas does the encasement for the declaration of independence contain?
The encasement for the Declaration of Independence contains a mixture of argon gas and filtered dry air to help preserve the document. Argon gas is commonly used in museum settings as it helps to inhibit the growth of mold and halts the degradation of the ink and parchment.
What gas is found in the display cases of the Declaration of Independence the Bill of Rights and the Constitution to help preserve them?

What happens when a gas is stretched?
You cannot stretch a gas. If you extend the volume in which some gas is enclosed you are working against the difference in between the external atmospheric pressure and the internal pressure of the gas. As you increase the enclosed volume, the pressure inside there falls and you have to work harder.
What happens to an enclosed gas if the temperature is increased?
For an enclosed gas (contained in a fixed volume), the pressure increases as temperature increases.Another way to picture this is that at higher temperatures, the gas molecules colliding with the walls of the container are more energetic, so the force exerted (pressure) is greater.
Is it legal to store compressed gas in an enclosed building?
it depends on what type of gas it is but yes if it carefully watched
