SUMMARY
The weight difference of an airtight building with an air capacity of 100,000 m3 is determined by the temperature and humidity of the air inside. On a winter day at -10°C heated to 20°C, the air density decreases, while on a summer day at 40°C cooled to 25°C, the air density increases. Utilizing the psychometric chart is essential for calculating the specific humidity and resulting weight changes due to varying temperatures. The calculations reveal that the weight difference is significant and directly related to the humidity levels during both seasons.
