Cholesterol
is dissolving a chemical or physical changeWell, it is not. Because you are not changing the chemical identity of the solid. It's still solid chemically and water chemically.
A solid and a liquid can form a solution, a suspension, the can chemically react, etc.
No, solid sulfur is not diatomic. Sulfur exists as S8 molecules in its solid form, with 8 sulfur atoms chemically bonded together to form a puckered ring structure.
Yes, the gas is a different state of matter.
It depends on the elements used. e.g. Burn solid, black carbon in oxygen and you get CO2. The C & O have both changed chemically as they share electrons. The solid carbon has now become a gas and is no longer black. That's a physical change, brought about chemically.
Yes, the daughter product resulting from radioactive decay can potentially react chemically with the surrounding solid matrix. This reaction may depend on the properties of the daughter product and the matrix material. It is important to consider these interactions when assessing the behavior of radioactive materials in a solid matrix.
The crust of the earth is the outermost solid shell of a rocky planet. This is chemically distinct from the underlying mantle.
It is a physical change because nothing chemically happened to it. It just formed to solid but,it is still the same substance.When you take it out of the freezer it melts.
No, water vapour is not in the solid form. Water vapour is the gas form of water and is represented chemically as H2O(g) where the (g) stands for gas.
As a substance melts, the molecules of the formerly-solid substance becomes less structured and drifts further apart.
the planets were named after the greek god and the godess
Its function is to digest food (mechanically and chemically), absorb nutrients and dispose of solid wastes.
