    A container has a gas that consists of positively charged ions. The gas undergoes a free expansion in which there is no heat exchange with surrounding. Does the temperature of the gas increases or decreases? Why?

    Why does the entropy of a solid increase on melting?

    Statement-1 : During irreversible adiabatic expansion of ideal gas entropy must increase. Statement-II : Increase in entropy of the system due to expansion is only partially compensated by decrease in temperature.

    Entropy ( S ) is a thermodynamic variable like pressure P , volume V and temperature T . Entropy of a thermodynamic system is a measure of disorder of molecular motion. Greater is disorder , greater is entropy. Change in entropy of a thermodynamic system is the ratio of heat supplied to absolute temperature.In an adiabatic reversible process, entropy remains constant while in any irreversible process entropy increases. In nature the processes are irreversible , therefore entropy of universe is continuoulsy increasing. When milk is heated , its entropy :
