Answer:
If temperature drops, it is negative feedback whereas if the temperature increases, it is positive feedback.
Explanation:
When the temperature drops from 98.30 °F, it means it is a negative feedback because its response is negative while if the temperature increases from 98.30 °F, it means it is a positive feedback because its response is positive. From 12 am to 3 am which represents negative feedback, temperature decreases whereas from 3 am to 6 am, the temperature increases which indicates positive feedback. From 6 am to 9 am, again the temperature drops and this fall represents negative feedback and so on.

Dry bulb (regular) air temperature is in the scale at the bottom. Relative humidity is in the curves. Trace up from 20 C until you get to 30%, then go from that point straight to the right to the edge where it gives you humidity ratio.
At 30% RH, air has an absolute humidity of 4.5 grams of water per kg of air.
At 40% RH, air has an absolute humidity of 6 grams of water per kg of air.
