What are the changes that matter undergoes?
Matter can undergo physical changes, such as changes in state (solid, liquid, gas) or shape, without altering its chemical composition. It can also go through chemical changes, resulting in new substances with different properties due to rearrangement of atoms or breaking of chemical bonds. Additionally, matter can experience nuclear changes, like radioactive decay, where the nucleus of an atom changes leading to the formation of different elements.
Are compounds created through physical changes?
No, only through chemical reactions. Physical changes never change the chemical makeup of something. For example, water tuning in to ice is a physical change. Ice and water both have the chemical symbol H20. On the other hand, a sodium - water reaction forms Sodium Hydroxide and Hydrogen. The compound, hydroxide, is formed.
Can all substances go through physical changes?
Yes, all substances can undergo physical changes. Physical changes do not alter the chemical composition of a substance, but rather change its physical properties such as shape, size, or state (solid, liquid, gas). Examples of physical changes include melting, freezing, boiling, or dissolving.
What 2 things can chemical and physical change go through?
Chemical changes involve the formation of new substances with different chemical properties, while physical changes involve alterations in the appearance or state of matter without changing the chemical composition. Chemical changes typically involve the breaking and forming of chemical bonds, resulting in new substances with different properties. Physical changes, on the other hand, involve changes in physical characteristics such as shape, size, phase, or state of matter without altering the chemical composition of the substance.
Is weathering a physical or chemical change?
Weathering can involve both physical and chemical changes. Physical weathering breaks down rocks into smaller pieces without changing their chemical composition, such as through freezing and thawing. Chemical weathering, on the other hand, alters the chemical makeup of rocks through processes like oxidation or dissolution.

Is it true that A physical change differs from a chemical change in that waste products are formed through chemical changes?
yes

What changes can't be reversed by physical means?
Changes that involve irreversible chemical reactions, such as burning wood to ashes or baking a cake, cannot be reversed by physical means. Once the chemical bonds are broken or rearranged, it is not possible to return the substances to their original state through physical processes alone.
What methods do scientist use to determine if it is a physical or chemical change?
Scientists distinguish between physical and chemical changes by examining if the change affects the chemical composition of the substances involved. Physical changes alter the appearance or state of a substance without changing its chemical makeup, while chemical changes result in the formation of new substances with different chemical properties through chemical reactions. Techniques such as observing color changes, production of gas, formation of a precipitate, or changes in temperature can help scientists identify whether a physical or chemical change has occurred.
Does sandstone go through physical or chemical weathering?
Sandstone can undergo both physical and chemical weathering. Physical weathering involves the breakdown of the rock through physical forces such as wind and water erosion. Chemical weathering, on the other hand, involves the alteration of the rock's composition through chemical reactions with elements like water and acids in the environment.
Does physical change differ from a chemical in that waste products are formed through chemical changes?
Yes, physical changes involve a change in the appearance or form of a substance without forming new substances. Chemical changes, on the other hand, involve the formation of new substances through the rearrangement of atoms. Waste products may be formed in chemical changes as new substances are produced.
