it is a physical change
No, a puddle of dirt is not a chemical change; it is primarily a physical change. When dirt becomes wet, its physical state changes as it absorbs water, but the chemical composition of the dirt remains the same. Chemical changes involve the formation of new substances, which does not occur in this scenario.
Separating rocks and dirt is a physical change because it doesn't change the identity of either substance.
Physical. It is still dirt/rock, no change to it's nature- just its position.
A landslide is only rocks/dirt moving so it is a physical change.
Yes, adding dirt to a puddle is a physical change. The dirt mixes with the water, but the chemical composition of both the dirt and the water remains unchanged. This process alters the appearance and texture of the puddle, but it does not create a new substance.
It is a physical process. Not really a change of any kind.
A landslide is a physical change because it involves the movement of rock and sediment down a slope due to gravity. There is no change in the chemical composition of the materials involved in a landslide.
Vacuuming is a physical change. It involves the removal of dirt and debris from surfaces without altering the chemical composition of those materials. The vacuuming process merely rearranges and collects particles, making it a physical action rather than a chemical reaction.
Soap molecules have non-polar and polar ends. When mixed with water, the soap dissolves, therefore having a physical change (but maintaining its chemical properties). The polar ends are in contact with water and consist of a salt, the non-polar ends are a long chain of hydrocarbons that do not mix with water.When soap molecules mix with water they form micelles, that consist of a bunch of molecules that in the center have the non-polar end (that traps dirt and other organic compounds) and in the exterior have the polar end in contact with water.
Mud
Washing clothes is a physical change, not a chemical change. The dirt and stains on the clothes are being physically removed, but the molecular structure of the clothes remains the same.
dirt is a mixture
