In this video, we explore why this happens and what it tells us about the air around us. You will learn about humidity — the amount of water vapour present in the air, and how it affects our weather. We also explain concepts like absolute humidity, relative humidity, and dew point in simple terms with everyday examples. By the end, you will understand why air feels dry or sticky, and why airplane trails form in the sky.
