Which property of matter changes during a chemical change but does not changes during a physical change?
The composition of matter changes during a chemical change as new substances are formed with different chemical properties. In contrast, the composition of matter remains the same during a physical change, with only the physical state or appearance of the substance being altered.
What is a characteristic that best describes what happens during a physical change?
A physical change involves a transformation in the appearance, shape, or state of a substance, while its chemical composition remains the same. This means that no new substances are formed during a physical change.
Do chemical changes affect the chemical structure of a substance?
Yes, chemical changes result in a change in the chemical structure of a substance. During a chemical change, new substances with different chemical compositions are formed through the rearrangement of atoms and bonds. This is in contrast to physical changes, where the chemical structure remains the same even though the physical properties may change.
Is fashioning a table leg from a piece of wood chemical or physical changes?
Fashioning a table leg from a piece of wood involves physical changes. The process of cutting and shaping the wood is a physical change as the composition of the wood itself remains the same, just the form and size are altered.
A chemical property of matter will stay the same during physical change?
A chemical property of matter, such as reactivity or flammability, remains unchanged during a physical change because physical changes only alter the state or appearance of a substance without affecting its chemical composition. For example, when ice melts into water, the chemical properties of H₂O remain the same, even though its physical form has changed. This distinction is crucial in understanding the differences between chemical and physical changes in matter.
Can new compounds form during a physical change?
no because in a physical change it does not change the chemical make up, however, it does during a chemical change
When matter changes in shape size or type but remains with the same substance?
That is a physical change. The chemical composition of the substance does not change during a physical change, only its physical properties like size, shape, or state of matter.
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.
What happens to the chemical makeup of matter when it undergoes a physical change?
During a physical change, the chemical makeup of matter remains the same. The atoms and molecules that make up the substance do not change their identities, only their arrangement or state. This means that no new substances are formed during a physical change.
Is steam turning into water chemical or physical?
Chemical changes are those in which the chemical composition of a substance changes during the process. But when steam turns into water or vice versa, only the physical state of the substance undergoes a change but the chemical composition remains same. Thus steam turning into water is a physical change.
How do physical and chemical changes affect mass?
law of consevation of mass states that the total mass before a chemical reaction is the same as the total mass after the chemical reaction
What property stays the same during physical or chemical changes?
The mass.
