Answer #1

Actually Joule is the unit of energy.

Energy = Force X Displacement

= F X S

Force = mass X acceleration

Force units Kg.m. s-2

Energy unts = Kg.m2.s-2

In Other terms we will try to define energy.

Pressure = Force / Area

Pressure = kg. m-1.s-2

Volume = m3

Pressure X Volume = (kg.m-1.s-2) X (m3) = kg. m2.s-2 = Energy units (Joules)

Usually, all the units of Pressure, Volume should be in SI Units to easily convert to Joules

Pressure units should be in Pascals. I.E. 1 atm = 101325 Pa

Volume = m3

Therefore, 1 Joule = 1 pa X 1 m3

Given 1 m3, and 7.5 atm

convert 7.5 atm to pascal

P=7.5 X 101325 = 759937 Pascal.

So, Energy (Joule) = P X V = 759937*1 = 759937 Joules/mol
