What are five changes made to air condition air?

Filtering: Air conditioners use filters to remove dust, pollen, and other particles from the air. Cooling: Air conditioners use refrigerants to cool and dehumidify the air. Ventilation: Air conditioners circulate and distribute the cooled air throughout the space. Humidity control: Air conditioners help regulate the relative humidity levels in a room. Air purification: Some air conditioners have additional filters or technologies to purify the air by removing contaminants and odors.

What data would be use to find out how much water vapor is in the air?

You can use a hygrometer to measure the amount of water vapor in the air. Hygrometers typically use a sensor to measure relative humidity, which can then be used to calculate the water vapor content in the air. Other methods include using a psychrometer or a dew point hygrometer.
