Why do boats float better in salt water rather than fresh water?
flotation is due to the fact the boat is less dense than the water, salty water is more dense than normal water. Consequently things can be heavier or more dense and still be less dense than water aka they float.
Why a grape didn't float in fresh water and why a grape didn't sink in salt water?
Salt water is much denser than fresh water and therefore can provide a much greater buoyant force.
Why do some things float in salt water but not in fresh water?
Because salt water can carry more objects than fresh water because the salt in the water makes the water heavier, and because fresh water has nothing in it so it's less heavier. Water cannot carry something heavier than itself. This heaviness is called density, and is the mass of the water in a particular volume of water. Pure fresh water has a density of 1g/mL, which means each milliliter of water has a mass of 1 gram. Anything that has a density greater than 1g/mL will sink in fresh water. The density of salt water is greater than 1g/mL, so anything that has a density less than the salt water will float on it, including fresh water.
Can an egg float better with salt?
An egg will sink in fresh water. Salt water is denser than fresh water, which allows the egg to float.
Why can we float easier in the sea than in a freshwater lake?
The density of salt water is higher than fresh water.
