The density of air is approximately 1.225 kg/m³, while the density of water is about 1000 kg/m³. This significant difference explains why objects generally float in air but can sink or float in water, depending on their density.
FAQs & Answers
- What is the density of air in kg/m³? The density of air is approximately 1.225 kg per cubic meter (kg/m³) under standard conditions.
- How does the density of water compare to air? Water is much denser than air, with a density of about 1000 kg/m³, which explains why objects can float or sink in water differently than in air.
- Why do some objects float in air but sink in water? Objects float or sink depending on their density relative to the fluid; since air is much less dense than water, objects are generally supported by air but may sink in water if they are denser.
