1. A closed vertical cylinder containing 0.3 kg of nitrogen at 90 °C is fitted with a weighted, frictionless piston so that a constant pressure of 275 kPa is maintained on the gas. The nitrogen is stirred by a paddle wheel inserted through the cylinder wall until the absolute temperature of the gas is doubled. During the process, 20 kJ of heat is transferred from the nitrogen to the surroundings. Determine the amount of paddle-wheel work required for this process. [Ans: -101.1 kJ]

Concept explainers

Entropy

In physics, entropy means the amount of disorder or the degree of randomness associated with a thermodynamic system. The system is not self-organized when the entropy of the system is high. For instance, when a system is at an elevated temperature, its molecules are in random motion, vibrating and colliding with each other. During this scenario, the probability of finding a molecule at a particular place twice, is low. Under this circumstance, the system can be said to be in a high entropy.
