Why is it that 1 litre of water weighs 1 kg while this doesn't apply for other liquids?
I have a question about the weight of water compared to other liquids. Why is it that 1 litre of water weighs 1 kg while this doesn't apply for other liquids?
That's a very interesting question! The reason why 1 litre of water weighs 1 kg is because of its density, which is about 1 gram per milliliter. This means that 1 liter of water has a mass of 1000 grams, which is equivalent to 1 kilogram.
