FREE EXPANSION

Gibb's Free Energy and Spontaneity | Thermal Expansion | Linear Expansion | Area Expansion | Volume Expansion | Buoyancy Problems

Suppose that the voulme of a certain ideal gas is to be doubled by one the following processes : (1) isothermal expansion (2) adiabatic expansion (3) free expansion in isulated condition (4) expansion at constant pressure . If E_(1),E_(2) ,E_(3) and E_(4) respectively are the changes in average kinetic energy of the molecules for the four processes, them :

An ideal gas expands from V to 2V in 4 separate processes. Where process 1 is isothermal process 2 is adiabatic, process 3 is free expansion and process 4 is isobaric. If E_(1),E_(2),E_(3) and E_(4) are the changes in average kinetic energy of the molecules in the isothermal, adiabatic free expansion and isobaric process respectively then choose the correct options.

One mole of an ideal gas is expanded isothermally jat 300 K from 10 atm to 1 atm . Find the values of DeltaS_(sys),DeltaS_(surr),& DeltaS_("total") under the following conditions . (i) Expansion is carried out reversibly (ii) Expansion is carried out irreversibly (iii) Expansion is free.
