Lemon and lime density differences explain why they float or sink

Lemons float in water while limes often sink due to slight density differences. Limes are slightly denser than lemons, causing them to sink, a phenomenon observed even after peeling. Researchers measured the lemon's density at 1.02 g/mL and the lime's at 1.12 g/mL, with water being approximately 1 g/mL.
