When carbon dioxide in air converts to more complex molecules by plants during photosynthesis is that a physical change?
No, the process of carbon dioxide being converted into more complex molecules by plants during photosynthesis is a chemical change, not a physical change. Chemical changes involve the formation of new substances with different chemical properties, whereas physical changes only affect the physical state of a substance without altering its chemical composition.
Is Curdling of milk a chemical change?
when milk curs it is a chemical change. A physical change is change in form, which is revesrable. Like water being frozen then thawed. A chemical change is irreversible, and involves a change in the chemical make up. What is happening is a new compound is being formed by the milk reacting with the air and such.
Is color and hardness examples of chemical properties?
This is False. The colour has to change to be a chemical change/property. If it stays the same, it is physical. Hardness is an example of a physical property. (ex. If I melt a piece of hard steel, it will become soft, liquid probably, but it isn't hard anymore, this change is reversible, therefore a physical change/property)
Black smoke from candle physical change or chemical change?
The black smoke produced from a burning candle is a physical change. This is because the change in appearance (from no smoke to black smoke) does not involve a change in the chemical composition of the candle wax or the oxygen in the air. The black smoke is primarily made up of tiny carbon particles that result from incomplete combustion of the candle wax.
Is rusting of iron a physical or chemical change?
Rusting of iron is a chemical change. It occurs when iron reacts with oxygen and water in the presence of moisture, forming iron oxide (rust). This process involves a chemical reaction that changes the chemical composition of the iron.
Is smoking a physical change or chemical change?
Smoking cigarette is a chemical process.
Is smoking a cigarette a physical or chemical change?
Smoking a cigarette involves a combination of physical and chemical changes. The act of lighting the cigarette and burning the tobacco involves a chemical change, producing new substances. The process of inhaling and exhaling the smoke is a physical change as it involves a change in state (from solid to gas) without altering the chemical composition of the smoke.
Is smoking a cigerrette a physical change?
It is a chemical change, even though the cigarette is getting physically smaller. When heat is added and you inhale the chemicals, the cigarette burns and you blow out smoke which in itself is a chemical reaction that cannot be reversed. Therefore, it's purely chemical. Remember that chemical changes cannot be reversed and physical changes can. Freezing water and then melting it is an example of a physical change. The example you mentioned is a chemical change.

Is pipe a chemical or a physical change?
Smoking is a chemical process.
What is an example of a physical rather than a chemical change an antacid sawdust or a cigarette?
Sawdust is not a change. Making solid wood into sawdust by sawing it, would be a physical change.
Is stapling an envelope a physical change or chemical?
A physical change
Is burning a cigarette a chemical change?
Yes
Is painting a door a physical or chemical change?
Physical change of the paint, not the door.
Is dry ice smoking at a concert is a physical or chemical change?
The process of dry ice sublimating, or turning directly from a solid to a gas, is a physical change. No new substances are formed, just a change in the physical state of the dry ice from solid to gas.
Is peeling an apple a physical or chemical change?
it is a chemical change
Is acidity physical change or chemical change?
An acid is a chemical compound, not a physical or chemical change.
Is crushing charcoal into powder a physical or chemical change?
Crushing charcoal into powder is a physical change, as it alters the size and shape of the charcoal without changing its chemical composition.
