Why do gallium silicon and bismuth expand on freezing?
Because all of them have orthorhombic solidification as crystalline solid.
Do most solids expand when cooled?
Generally speaking, substances have the least amount of surface area as a solid, as they are heated they form a liquid and expand, as this is heated it forms a gas and expands more. *Assuming pressure is constant **Water is the only substance to expand as it freezes
How many grams and moles are in Bismuth?
Depends on how much of the sample there is.
What happens to most materials when it is on cooling?
Most materials solidify when they are cooling. The molecules slow down and begin to arrange themselves closer together. Some materials have an opposite reaction.
Is bismuth nitrate same as bismuth oxynitrate?
No, the first is Bi(NO3)3 = Bismuth nitrate; it has 3 NO3- ionsand the other is BiO(NO3) = Bismuth oxynitrate, also called Bismuth subnitrate
How much of bismuth and polonium is in coke?
Coke doesn't contain polonium or bismuth.

How much does water expand by?
On heating. water molecules expand till they reach 100 cecius and break free from each other and turn into vapor. On cooling, when the temprature is 4 degree celcius, water starts to expand till it freeze.
Does water expand when cooled?
Water shrinks on cooling upto 4o C. But on further cooling it expands.
How do you grow Bismuth crystals?
Bismuth can be melted in a stainless steel pot atop a kitchen stove and very slowly cooled. The excess should then be poured into a stainless steel pot and depending on the length and evenness of the cooling process the crystals will be formed during the cooling period. Simple and easy. Requires 99.99% pure elemental metal or greater.
Is Bismuth a metal or a non-metal?
No, Bismuth is a metal
Why the surface of ice raises when it changes from water into ice?
water contracts when cooling until about 4 deg. C. From that temp. further cooling causes the water to expand. as it freezes it continues to expand, that is why ice floats.
What two pure substaces expand when frozen?
1. water 2. silicon 3. bismuth 4. antimony 5. gallium pick two.
How many grams and moles are in Bismuth?
Depends on how much of the sample there is.
What element is used in pink anti-diarrhea medication?
bismuth bismuth bismuth
Why is water the only substance that expands when frozen?
Nope. Silicon(Si), Gallium(Ga), Antimony(Sb), Bismuth(Bi) and acetic acid(CH3COOH, vinegar) all expand on freezing as well. Moreover, silicon expands more than water on freezing (10% compared to waters 8%). The trick to this is that any substance with an open tetrahedral molecular structure will also expand upon freezing. (Perhaps phosphorus oxide(s))
