A gas expands such that its initial and final temperatures are equal. Also the process followed by the gas traces a straight line on the P-V diagram (i) The temperature of the gas remains constant throughout (ii) The temperature of the gas first increases and then decreases (iii) The temperature of the gas first decreases and then increases (iv) The straight line has negative slope

The work done by the gas in the process shown in given P-V diagram is

A gas took part in three thermal processes in which it is heated from the same initial state to the same final temperature. The process are shown in the P-V diagram by straight lines 1-2 , 1-3 and 1-4 . Q_(1) , Q_(2) and Q_(3) are amount of heat supplied to the gas in the process 1 to 2 , 1 to 3 , 1 to 4 . respectively.

A gas take part in two thermal processes in which it is heated from the same initial state to the same final temperature. The processes are shown on the P-V diagram by straight lines 1 rarr 3 and 1 rarr 2

If a gas, at constant temperature and pressure expands, then its

In a real gas the internal energy depends on temperature and also on volume. The energy increases when the gas expands isothermally. Looking into the derivation of (C_p - C_v = R_1) find whether (C_p - C_v) will be more than R, less than R, or equal to R for a real gas.

Six grams of hydrogen gas at a temperature of 273 K isothoermally expanded to five times its initial volume and then isochorically heated so that the pressure in the final state becomes equal to that in the initial state. Find the total amount of heat absorbed by the gas during the entire process.

1 mol of a gas is changed from its initial state (15 L, 2 atm) to final state (4 L, 10 atm) . If this change can be represented by a straight line in P-V curve, calculate the maximum temperature that, the gas attained.

One mole of a gas changed from its initial state (15L,2 atm) to final state (4L,10 atm) reversibly. If this change can be represented by a straight line in P - V curve maximum temperature (approximate), the gas attained is x xx10^(2) K. Then find the value of x.
