At what temp will a gas be at if you allow it to expand from an original 456 ml to 65°c to 3.4 l

Answer : The initial temperature of gas will be, 45.33 K

Explanation :

Charles' Law : It is defined as the volume of gas is directly proportional to the temperature of the gas at constant pressure and number of moles.

or,

where,

= initial volume of gas = 456 ml  = 0.456 L

conversion used : (1 L = 1000 ml)

= final volume of gas = 3.4 L

= initial temperature of gas = ?

= final temperature of gas =

Now put all the given values in the above formula, we get the initial temperature of the gas.

Therefore, the initial temperature of gas will be, 45.33 K

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.
