An auditorium is designed to seat 200 people. The ventilation rate is 2.50 x 10 m' h of outside air, or 3.3 x 10' kg/h. The outside temperature is -10°C dry- bulb, and the outside pressure is 101.3 kPa. Air leaves the auditorium at 23°C dry-bulb. The air temperature entering the auditorium is 21.6°C. Most nearly, how much heat should be supplied to the ventilation air? C. 540 kW D. 780 Kw A. 120 kW B. 290 kW

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.
