It is a physical change because is it changing the leaf? No, no it isn't so it is a physical change.
A chemical change is a change in which a substance turns into a completely different substance that can't be reversed. A chemical change often happens when a substance burns (not to be confused with evaporation or melting of a substance), changes colors, a substance spoils or rusts, photosynthesis or respiration, and/or a substance tarnishes.Some examples are a bike rusting, burning bread to make toast, fireworks exploding, milk spoiling, a leaf changing color, mixing eggs and flour for a batter, baking a cake, etc.A chemical change will NOT dissolve, go through a state of matter (sublimation, decomposition, melting, freezing, evaporation, and condensation), breaking or tearing of a substance, and/or anything that can be reversed back.A chemical change is one in which one or more new substances are formed. Simple examples include burning and rusting.
Violet, blue, and red are the colors your eye responds to most when looking at a green leaf.
because the leaf is non polar or Because the leaf is coated in lipid molecules
Yes, the leaf is considered a plant organ.
Stomata on the underside of the leaf control the passage of gases into and out of the leaf.
Making salt by mixing sodium and chlorine is it a physical or chemical which one
Chemical
It is a chemical change, a degradation of the compounds from the leaf.
The change is leaf color is a chemical change.
chemical
The decay of organic matter such as leaves is a chemical change.
Crushing a leaf is a physical change, not a chemical change because the chemical composition of the leaf remains the same before and after crushing. However, if the crushing process causes the leaf to release certain chemicals due to breaking of cell walls, then it can result in a chemical change.
Chemical. It has to do with the closing of the part that connects the leaf to the tree and the lack of nutrients causes the leaf to turn colours.
The color change in a leaf typically indicates a chemical change when it results from the breakdown of chlorophyll and the revealing of other pigments, such as carotenoids and anthocyanins, as the plant prepares for winter. This process involves biochemical reactions that alter the pigments present in the leaf. Conversely, a physical change may be indicated if the color change is due to external factors like exposure to light or temperature without altering the leaf's chemical composition.
Photosynthesis makes a leaf green so when it turns brown it has stopped doing photosynthesis so most likely it is chemical change. Helpful enough? :|
Drying wood in a shed does not result in a chemical change because the process involves the removal of water through evaporation, which is a physical change. The structure and composition of the wood remain the same.
