changes color, fizzing, foaming, or the production of heat, light, sound or odor.
It is a sign that a chemical change is taking place, rather than a physical change.
chemical change
Formation of bubbles or gas: Gas evolution can indicate a chemical reaction is occurring. Change in color: A sudden change in color could be a sign of a reaction, such as a shift from clear to cloudy. Temperature change: If the reaction generates heat (exothermic) or absorbs heat (endothermic), it can be an indication that a chemical reaction is taking place.
formation of a solid and release of heat. apex
No, freezing nitrogen gas does not involve a chemical change. It is a physical change where the nitrogen gas transitions from a gaseous state to a solid state without any chemical reactions taking place.

A chemical change is taking place.
A chemical reaction is; when there is a chemical change taking place from energy or shifting of molecular structure.
first when there's a physical change in the substance second there will be a solution or a formula to that substance third is, it involves temperature fourth is change in color of the substance fifth is the bubbling of another substance is yet an another clue that a chemical reaction has occured.
Because no chemical reaction is taking place. It is the same substance, just in a different state of matter.

Physical because no reaction is taking place.
No. It is a physical change. The chemical formula for water is H2O, and that is also the chemical formula for ice. So there is no chemical change taking place, only a change in the state of matter.
No, adding hydrochloric acid (HCl) to magnesium (Mg) and observing the resulting chemical reaction is a chemical change, not a physical change. The reaction produces hydrogen gas and magnesium chloride, with new substances formed.
