Is buoyancy a physical or chemical change?
Buoyancy is a physical change, not a chemical change. It results from the relationship between an object's density and the density of the fluid it is placed in, causing the object to either float or sink.
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"
Is a hot air balloon rising a chemical change?
No, a hot air balloon rising is a physical change, not a chemical change. The balloon rises because the air inside it is heated, causing it to expand and become less dense than the surrounding air, which causes it to float upwards.
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.
How do you know if a chemical will float in water?
A chemical will float in water if its density is less than the density of water (approximately 1 g/cm3). This can be determined by comparing the densities of the chemical and water. If the chemical's density is less than water, it will float; if it is greater, it will sink.

Is flotation a physical change or chemical change?
Floating is not a change of any kind. It is a physical property, dependent on its density.

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
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.
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.
How do you know if a chemical will float in water?
A chemical will float in water if its density is less than the density of water (approximately 1 g/cm3). This can be determined by comparing the densities of the chemical and water. If the chemical's density is less than water, it will float; if it is greater, it will sink.
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.
