High humidity can make a hot day miserable and sticky, but what is humidity, really? Humidity refers to the amount of water vapor in the air, impacting how hot or cool it feels outside. Absolute humidity measures the actual amount of water vapor present, while relative humidity compares it to the maximum the air can hold at a given temperature. This explains why high-humidity makes hot days feel even hotter! #humidity #weather #summer | Howstuffworks

How do instant cold packs work? 🧐🥶 Instant cold packs work by using an endothermic reaction: you squeeze the pack to break an inner bag of water, which mixes with a solid compound like urea or ammonium nitrate. This mixing process absorbs heat from its surroundings, including the air and anything the pack touches, making it feel cold! #science #physics #technology #knowledge #howitsmade | Learning with Lyrics
