Let `Delta U_(1)` and `Delta U_(2)` be the changes in internal energy of an ideal gas in the processes `A` and `B` then

Change in internal energy in an isothermal process for ideal gas is

Change in internal energy in an isothermal process for ideal gas is

An ideal gas undergoes an expansion from a state with temperature T_(1) and volume V_(1) through three different polytropic processes A, B and C as shown in the P - V diagram. If |Delta E_(A)|, |Delta E_(B)| and |Delta E_(C )| be the magnitude of changes in internal energy along the three paths respectively, then :

An ideal gas is taken from state A to state B via three different processes as shown in the pressure volume (P-V) diagram. If Q_1 , Q_2 & Q_3 indicates the heat absorbed by the gas and Delta U_1 , Delta U_2 & Delta U_3 indicate change in internal energy in three processes, then

If the internal energy of an ideal gas U and volume V are doubled, then the pressure
