Answer:
C. Increasing the temperature of the parcel
D. Increasing the mixing ratio of the parcel
Both C and D will increase the virtual temperature of the parcel
Step-by-step explanation:
A change in temperature of the air can likewise change the relative moistness. Dew Point is the temperature to which a package of air must be cooled, at steady weight and water vapor content, for immersion to happen. Dew point is resolved regarding a level surface of the water.
Supreme moistness is equivalent to the mass of water vapor partitioned by the complete volume of air or water vapor thickness. Total stickiness changes as the volume of air package changes.
