Free Expansion

Expansion of a gas in vaccum is called free expansion.Calculate the work done and the change in internal energy when 1 litre of ideal gas expands isothermally into vaccum until its total volume is 5 litre?

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.

A rod of steel is 5m long and 3cm diameter at a tempearatyre if 20^(@)C . Find the free expansion of the rod when the temperature us raused ti 65^(@)C . Find the respective pulls exerted if (i) the ends do not yield and (ii) the ends yield by 0.12 cm. Y = 2 xx 10^(5) MN // m^(2) and alpha = 12 xx 10^(6) per ^(@)C

A rod of length 2 m is at a temperature of 20^@ C. find the free expansion of the rod, if the temperature is increased to 50^@ C, then find stress produced when the rod is (i) fully prevented to expand, (ii) permitted to expand by 0.4mm. Y=2xx10^(11)N//m^(2), alpha=15xx10^(-6//^(@))C .
