Answer 1 : d that is More, Higher
Explanation: 40F air consists of 5gram of vapour at saturation and its relative humidity is 100% and 100F air has a relative humidity of 25. For air to saturate at 100F the vapour content must be 45 gram and 25% of 45 gram is 11.25 gram so 100F has 11.25 gram of vapour more than cold air (5 gram) and it is relative humidity is 25 which is less than cold air (100%).
Answer 2 C windward, orographic
Explanation: when air more upward on a hill in the windword direction it gets cools and precipitate this windward movement and adiabatic cooling to form cloud is called orographic process.
Answer 3 C
Explanation : Wien law = 2897 micrometer/T = wavelenth emit
2897/1200 =0.25 micrometer
Answer 4 decrease, remain same
with the increase in temp the capacity of air to become saturated increases and relative humidity is a ratio of vapour present currently divided by the vapour amount at saturation. Since our earlier term is constant and later increases so ratio decrease. Dewpoint will remain same.
