How are all physical changes alike?
All physical changes involve a change in the form, shape, or state of matter without altering the chemical composition of the substance. This means that the particles in the substance remain the same before and after the change, only their arrangement or state is altered.
Is cutting paper a chemical?
No, cutting paper is a physical change, not a chemical change. The paper's chemical composition remains the same before and after cutting; only its physical shape is altered.
Is slicing a bread a chemical or a physical?

Does wood undergo a physical change before it burns?

How nature filters water as it travels to underground aquifers?
As water travels through the soil and rock layers, particles and contaminants are filtered out by physical straining, absorption, and chemical reactions. The soil and rock act as natural filters, trapping impurities and allowing cleaner water to gradually percolate down to underground aquifers. This natural process helps to clean and purify the water before it is stored in these underground reservoirs.
What breaks down human waste?
Human waste is primarily broken down by bacteria in the colon and gastrointestinal tract. This process involves the breakdown of food particles and absorption of nutrients, with the remaining waste expelled from the body through bowel movements. Wastewater treatment facilities further break down human waste through a combination of physical, chemical, and biological processes before it is discharged safely into the environment.
