In a quasi-static isobaric expansion, 700 J of work are done by the gas. If the gas pressure is 0.40 atm, what is the fractional increase in the volume of the gas, assuming it was originally at 22.0 L?

Answer : The fractional increase in the volume of the gas is, 1.78

Explanation :

Formula used to calculate the work done by the gas in quasi-static isobaric expansion is:

Isobaric means, at constant pressure.

where,

w = work done by the gas = 700 J = 6.909 L.atm    (1 L.atm = 101.32 J)

p = pressure of the gas = 0.40 atm

= final volume = ?

= initial volume = 22.0 L

Now put all the given values in the above formula, we get:

Now we have to calculate the fractional increase in the volume of the gas.

Fractional increase in the volume of the gas =

Fractional increase in the volume of the gas =

Fractional increase in the volume of the gas = 1.78

Thus, the fractional increase in the volume of the gas is, 1.78

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
