What is an ideal gas?

For an ideal gas, number of moles per litre in terms of its pressure 'P', gas constamt 'R' and temperature 'T' is

For an ideal gas, an illustration of three different paths A, (B +C) and (D+E) from an initial state P _(1) , V _(1), T _(1) to a final state P _(2), V _(2), T _(1) is shown in the given Path A represents a reversible isothermal expansion from P _(1), V _(1), to P _(2), V _(2) Path (B +C) represents a reversible adiabatic expansion (B) from P _(1), V _(1), T _(1) to P _(3), V _(2) , T _(2) followed by reversible heating the gas at constant volume (C) from P _(3), V _(2), T _(2) to P _(2), V _(2), T _(1). Path (D+E) represents a reversible expansion at constant pressure P _(1) from P _(1) , V _(1), T _(1) to P _(1), V _(2), T _(3) followed by a reversible cooling at constant volume V _(2) (E) frm V _(1) , V _(2) T _(3) to P _(2) , V _(2), T _(1). What is Delta S for path A ?

What is Delta S for path A ?

One mole of an ideal gas is allowed to expand reversibly and adiabatically from a temperature 27^(@)C. If work done during the process is 3kJ final temperature of the gas is ( C_(v) = 20 JK^(-1) mol^(-1)]

BY connecting three gas laws like Boyle's law, Charles law and Avogadro's law, we get ideal gas equation Universal gas constant R is there in the ideal gas equation. Calculate the mass of 740 ml of O_2 at 125^@C and 750 mm Hg pressure.
