Why does Marvel need a water-superhero character? | H20 structure, hydrogen bonds, vital properties
Ever wonder why high humidity makes the heat feel worse, or why homemade frozen fruits go mushy, and how nutrients rise from the soil even in 100-meter-tall trees? It’s all about water’s amazing hydrogen bonding power rooted in its unique structure. So let’s dive in!
