FAQs & Answers

  1. How does the weight of water change with temperature? The weight of water does not change significantly with temperature, but its density does vary slightly.
  2. What is the density of water at different temperatures? Water's density is approximately 1 kg/L at 4°C, which is its maximum density.
  3. How do you convert liters to kilograms? Since the density of water is approximately 1 kg per liter, 1 liter of water equals 1 kilogram.
  4. What other liquids have similar densities to water? Some liquids like alcohol can have densities close to water, but they generally vary and must be checked individually.
