Why is mining coal a physical change?
Mining coal involves extracting it from the ground through processes such as drilling, cutting, and blasting. This is considered a physical change because the coal itself is not altered at a molecular level during the mining process—it is simply being removed from its original location.
What happens to something if you pulverize it?
When something is pulverized, it is crushed or ground into very small pieces or powder. This can change its physical properties and make it easier to handle or mix with other materials.
What is the force that is pulling you down to the ground?
The force pulling you down to the ground is gravity, a natural phenomenon by which all physical bodies attract each other.
Regan has an empty glass cup. It has a mass of 0.3 kg. She drops the cup on the ground and it shatters into several pieces. If she collected all of the pieces of the cup how much mass would all of the?
The total mass of all the pieces would still be 0.3 kg since mass is a conserved property.
What is the name of the force that holds things to the ground?
Gravity is the force that holds things to the ground. It is a natural phenomenon by which all physical bodies and particles with mass are attracted to each other.
Is ground flour an example of chemcal change?
No. That is a physical change.
Is ground floor a chemical change?
If you mean ground flour, then no. Grinding flour is a physical change because there is no change in chemical composition.
Is a ground up sugar cube a physical change?
yes, theres is not change to it's molecular structure
Is a metal surface being ground a chemical change?
A metal Surface being ground is a physical change, not a chemical change.
Does sugar crystal undergo a physical change when ground?
Yes, when sugar crystals are ground into smaller pieces, it is considered a physical change since the chemical composition of the sugar remains the same. The change in the size and shape of the sugar crystals is a result of physical forces acting on the substance, rather than a chemical reaction occurring.
Is a wheat ground into flour into a chemical change?
Physical, the chemical properties of the wheat are still the same.flour is ground by a physical change
Using a meat grinder you were able to obtain ground meatwhat kind of change in matter did you produce?
The change in matter produced by using a meat grinder to obtain ground meat is a physical change. This is because the composition and properties of the meat remain the same before and after grinding, only the physical form has changed.
Is making peanut butter a physical or chemical change?
It's a physical change, but not much of one.
Is it physical or chemical change a candle wax falls on the ground and cools?
Cooling, and changing from a liquid to a solid are physical changes, not chemical changes. The chemical composition of the paraffin does not change.
Sleet is a physical or chemical change?
Sleet is a physical change because it is the result of rain freezing as it falls through a layer of cold air near the ground. The change from rain to sleet does not involve a chemical reaction, but rather a change in state from liquid to solid.
Is ground flour a result of a chemical change?
No, grinding flour is a physical change, not a chemical change. The process of grinding wheat into flour involves only a change in the appearance and size of the wheat grains, without altering their chemical composition.
Is a leaves fall to the ground and begin to rot a chemical or a physical?
It is a chemical change. The substance of the leaves is changing.
