A cubic metre of dry air at NTP is allowed to expand to 5 cubic metres (i) isothermally, (ii) adiabatically. Calculate in each cae, the pressure, temperature and work done. ( gamma=1.4 and 1 atm=1.013xx10^(5)Nm^(-2) )
Two gases have the same initial pressure, volume and temperature. They expand to the same final volume, one adiabatically and the other isothermally
In the previous question, if the two gases are compressed to the same final volume,
Statement-1: Two gases at same pressure, volume & temperature are compressed to same volume. The first isothermally and second adiabatically, greater work is done on the gas for an adiabatic process. Statement-2: Final temperature for gas going under isothermal process is more than gas going under adiabatic process.
Two different ideal diatomic gases A and B are initially in the same state. A and B are then expanded to same final volume through adiabatic and isothermal process respectively. If P_(A), P_(B) and T_(A), T_(B) represents the final pressure and temperature of A and B respectively then.
Two samples A and B of the same gas have equal volumes and pressure. The gas in sample A is expanded isothermally to four times of its initial volume and the gas in B is expanded adiabatically to double its volume. It work done in isothermal process is twice that of adiabatic process, then show that gamma satisfies the equation 1-2^(1-gamma) =(gamma-1)In2 .
Two sample A and B of a gas initially at the square at the same pressure and temperature are compressed from volume V to V//2 (A isothermally and B adiabatically). The final pressure of A is
