Is lithium metal light enough to float on water a physical change?
Your question makes no sense. If stripped down, your question looks like this: "Is metal change?" The answer to this question is obviously "no, but some change is metal, such as pennies or nickels"
Krypton gas floats above air is it a chemical or physical?
It is a physical property. Any gas that has a lower density than air will float above air. This is similar to how if you pour oil into water. The oil will float on the water because it is less dense.
What chemical makes copper float?
If it is a thin, small piece of copper put it in water with soap and I think it will float Copper will float in Mercury. Copper will float in Uranium Hexafluoride but good luck getting your hands on any of that.
What are the physical and chemical properties of the raft that would be important to ensure your safety?
First make sure it can float. Then make sure that the materials used will not corrode too quickly, especially in salt-water. It would be advantageous to have a sail or a rudder. Shelter from the sun and a place to store food & water are essential.
Do wax sink or float?
Float.
Is flotation a physical change or chemical change?
Flotation is a physical change. It involves changing the density or buoyancy of an object in a liquid to make it float or sink. There is no chemical reaction taking place during flotation.

Is shaking up salad dressing and sewing an apron a physical change?
No. They aren't even a mixture, since they don't mix. When properly shaken prior to serving, an oil & vinegar dressing is a "suspension"; droplets of each all next to each other, but still separate. If you leave the bottle standing for a few minutes, the vinegar (which is mostly water) will sink to the bottom and the oil will float to the top.
How did the scientific vies of nature change during the scientific revolution?
by making boats that float
How could you prove that dissolving table salt in water is a physical change or not a chemical change?
well you know its not a chemical change when you see the salt dissolving because if your were to put something else like sugar then it would be a chemical change because the sugar would just float right to the bottom and stay there but salt would go around in the water and start dissolving.
What the effects of chemical density?
Density is a physical property; the unit in SI is Mg/m3. Materials with density under 1 float on water.
Is making an egg float in salt water chemistry or science or physics?
Density is physical, that's what 'egg-floats-in-salt-water-' is all about.
Is buoyancy a chemical property?
Yes, buoyancy is considered a physical property. It is a type of physical property because it is related to the density and weight of the item, which are both physical.
Why does a lifebouy float?
because there is a chemical named"fridofloat" in it
What does salt have that can make an egg float?
it has density when dissolved in water making an egg float.
Boiled egg float or sink?
float....when you boil an egg it starts out at the bottom and as the insides harden, making it ready for consumption, it will float.
