Physical. Physical changes include things such as changing shape or color. Chemical changes change the chemical properties of a material, often during a chemical reaction.
Is mixing cement a chemical or physical change?
Actually both physical and chemical changes are happening during cement mixing.
What happens to matter and energy during a chemical reaction?
Conserved.
What changes occur to raw materials during the paper making process?
Papermaking is a series of physical and chemical changes. The physical and chemical changes will depends on raw material used and grade of paper manufactured. For a typical north American paper mill which uses wood for making copying paper, following changes will take place. Operation Type of Change Logging Physical Barking (Removal of bark) Physical Chipping Physical Screening Physical Cooking Chemical Washing Physical Chemical Recovery Chemical Bleaching Chemical Washing Physical Refining Physical Sizing Chemical & Physical Screening Physical Cleaning Physical Wet-end chemical addition Chemical & Physical Sheet Formation Physical Pressing Physical Drying Physical Calendaring Physical Winding Physical Rewinding Physical Cutting Physical
Why is mass conserved during the combution of methane?
Its conserved during the combustion of anything - the mass of the products is always equal to the mass of the materials that react.

How can you tell if a physical reaction is occuring?
During a physical change the chemical molecule is not affected; physical changes are changes of phase or form.
Is mixing cement a chemical or physical change?
Actually both physical and chemical changes are happening during cement mixing.
What property stays the same during physical or chemical changes?
The mass.
What are the differences betwen physical and chemical changes in terms of what happenes to molecules?
During a chemical change the molecule is transformed; during a physical change the molecule is not transformed.
Is seeds to pumpkin physical or chemical change?
This process involve chemical reactions but also physical changes.
What is a characteristic that best describes what happens during a physical change?
There are no chemical changes.
How do the particles that make up matter compare during physical and chemical changes?
The particles that make up matter are unchanged during physical, or chemical changes. Matter can neither be created nor destroyed, only transformed.
What happens to matter and energy during a chemical reaction?
Conserved.
Can a substance produced during a physical change easily change back?
Yes. Chemical changes are irreversible, but physical changes can easily be changed back
Which part of the atom remains the same during physical and chemical changes?
i believe it is the nucleus.
