A rigid tank initially contains an ideal gas at 100 kPa and 30 C. Heat is then transferred through the tank until the ideal gas is at 120 kPa and 80 C. The mass of the ideal gas is 0.9 kg. Assume that the constant pressure specific heat (Cp) of the ideal gas is constant and equal to 15 kJ/kg-K. Also, the gas constant (R) and the molar mass (M) of carbon dioxide are R = 0.35 kJ/kg-K M = 44.01 kg/kmol In the question that follows, select the answer that is closest to the true value. What is the change in entropy of the ideal gas during this process in units of kJ/K ?

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.
