How do convention currents move?
Heated from the bottom, the warmer substance will slowly rise to the top while the cooler substance at the top falls to the bottom to be heated again. Look at a lava lamp. That is all about convection currents.
Is rust made of separate atoms or molecules?
Rust is primarily composed of iron oxide, which consists of iron and oxygen atoms bonded together in a specific arrangement. While iron and oxygen exist as individual atoms, in rust, they combine to form molecules. Therefore, rust is made up of these molecules rather than separate atoms.
What is the difference between 2Br and Br2?
2Br is two separate bromine atoms. Br2 is a bromine molecule, consisting of two bromine atoms bonded together.
Is it possible to separate iron and sulfur after being heated?
Yes, it is possible to separate iron and sulfur after being heated. One common method is using a magnet to separate the iron, as it is magnetic, while the sulfur remains in its powdered form. Another method is to dissolve the mixture in a solvent, filter out the solid sulfur, and then evaporate the solvent to recover the separated components.
What is the effect by which an object begins to glow while heated?
When an object begins to glow while heated, it is due to incandescence, which is the emission of electromagnetic radiation (often in the form of visible light) as a result of being heated to high temperatures. As the object's temperature increases, the atoms or molecules within the object gain energy, causing them to emit light as they return to a lower-energy state.
Distillation and evaporation are methods to .?
Distillation is a method of separation for liquids.Evaporation is a physical change, from liquid to gas.
Does olivine form to anything when heated?
can heat form while heated
How do you stop cream from splitting while cooking?
If you mean curdling , you need to heat the cream slowly and not add it to a hot mixture when it is cool. If cream is needed to be added to a hot mixture, slowly heat the cream to mixtures temperature in a separate pot and add it when it is hot.
Does sodium sulfate have iodine in it?
No, sodium sulfate does not contain iodine. Sodium sulfate is composed of sodium, sulfur, and oxygen atoms, while iodine is a separate chemical element.
Are lattice and cohesive energies same?
Lattice energy is energy required to separate ions to infinite distance with no more interaction. Cohesive energy is energy required to separate atoms to infinite distance with no more interaction.
Why it is easier to separate water drops than to separate a solid in to small pieces?
In a solid, the atoms are bound together by stronger forces.
Does water lose mass while heated?
no
