Adevice that uses the wet/dry bulb method to measure the the sling psychrometer. as seen here, two thermometers are attached to a handle or length of rope and then are spun around in the air for a few minutes.

relative humidity

Explanation:

In general, a psychrometer is an instrument composed of two thermometers, used to measure the relative humidity of the air with high precision. As seen in the question above, the two thermometers allow a simultaneous measurement of the temperatures of the wet bulb and the dry bulb. Meteorologists usually use a more efficient form of the psychrometer to measure relative humidity, which is the sling psychrometer.

Chloroplasts convert solar energy into simple sugars which are then used by the mitochondria to provide energy for the cell.
