A gas in a rigid container has a pressure of 3.5 atm at 200. k calculate the pressure at 273 k

4.78atm

Explanation:

From the question, we obtained the following:

P1 (initial pressure) = 3.5 atm

T1 (initial temperature) = 200K

T2 (final temperature) = 273K

P2 (final pressure) =?

Using P1/T1 = P2/T2, the final pressure can be obtained as shown below:

P1/T1 = P2/T2

3.5/200 = P2/273

Cross multiply to express in linear form as shown below:

200 x P2 = 3.5 x 273

Divide both side by 200

P2 = (3.5 x 273)/200

P2 = 4.78atm

Therefore, the pressure at 273K is 4.78atm

i believe that it is a exoplanet

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
