A sample of an ideal gas expands reversibly and isothermally at 300 K from a volume of 2 L to 10 L. The number of moles of the gas is 1 mole.
Calculate the work done by the gas during the expansion.
Use the formula for reversible isothermal expansion:
w = -nRT lnleft(frac{V_2}{V_1}right)

Chemistry ek bahut bada subject hai. Kya aap Atomic Structure, Chemical Reactions, ya Periodic Table ke baare mein
Method used for separation of mixture of products obtained in the following reaction is
In liquids particles are loosely packed,it has weaker interparticle forces than solids,it has no definite shape nor a definite volume,particles of liquids can slide over each other and allows force,liquids has no effect of pressure and are highly incompressible.
The objectives of the question were to analyze to role of organic chemistry in our daily life.
