No, it's a change of state. Water vapour when cooled goes back to the state of water, which means it hasn't changed chemically.
no. chemical reaction requires a new substance to be created
NO!!! It is a PHYSICAL change of phase between gas and liquid.
Glass of water sweating is a physical process caused by condensation of water vapor from the air onto the cooler surface of the glass. It does not involve any chemical reactions.
No, this is definitely a physical change, absolutely not a chemical.
Condensation of water vapor is a physical change. It involves the transition of water from a gaseous state (vapor) to a liquid state without altering its chemical composition. The process is reversible; if the liquid water is heated, it can evaporate back into vapor.
no. chemical reaction requires a new substance to be created
It is physical, change of state, just cooling down
Vapor is not a chemical reaction itself. It is the gaseous state of a substance that was previously in liquid or solid form. The process of creating vapor from a liquid or solid can involve a physical change (such as evaporation) rather than a chemical reaction.
NO!!! It is a PHYSICAL change of phase between gas and liquid.
it would be a chemical reaction mArKe ^_^
vapor
Glass of water sweating is a physical process caused by condensation of water vapor from the air onto the cooler surface of the glass. It does not involve any chemical reactions.
Cooking an onion involves both chemical and physical changes. The heat causes physical changes such as softening and browning of the onion as well as chemical changes such as the breakdown of complex molecules into simpler compounds, resulting in new flavors and aromas.
Burning anything (a liquid or a solid) is a chemical change and the reaction is known as a combustion reaction.
Burning propane is a chemical change because it involves a chemical reaction where the propane combines with oxygen to produce carbon dioxide and water vapor. This reaction results in the formation of new substances with different properties than the original propane.
Charcoal burning on the grill is a chemical change because the charcoal undergoes a chemical reaction with oxygen to produce heat and new chemical compounds like carbon dioxide and water vapor.
No, this is definitely a physical change, absolutely not a chemical.
