If a place has high actual water vapour but very high temperature how can relative humidity be?

Correct answer: जरूरी नहीं कि बहुत अधिक हो

Correct answer: A. Relative humidity is the amount of water vapour actually present compared with the maximum amount the air could hold at the same temperature, usually expressed as a percentage. Warm air can hold more water vapour before reaching saturation than cold air. Therefore, a hot place may contain a large absolute amount of vapour but still have moderate or even relatively low relative humidity if its moisture-holding capacity is much larger. Option A is correct because high actual vapour does not automatically mean that the air is close to saturation. Option B is wrong because 100% relative humidity occurs only when the air is saturated at that temperature, not simply whenever actual moisture is high. Option C is wrong because the presence of water vapour means relative humidity is not necessarily zero. Option D is physically impossible in the ordinary definition because relative humidity is not negative. A useful example is that the same amount of vapour can produce a higher relative humidity in cool air and a lower relative humidity in hot air. Memory cue: relative humidity depends on both moisture present and temperature-dependent capacity.
