What are the differences between physical and chemical changes?
Physical changes involve a change in appearance or state of matter without altering the chemical composition, while chemical changes result in the formation of new substances with different chemical properties.
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.
What are the differences between the physical and chemical?
in changes. Physical changes can be reversed. E.g. if you were to melt a block of ice, and then freeze it again, it would to some degree be reversed. This is a physical change. However, if you were to burn a peace of toast, the change would be chemical. Once the toast is burnt you cant get it back.
What is the differnce between physical and chemical change?
Physical changes are changes in appearance, state, or form of matter without altering its chemical composition. Chemical changes involve the formation of new substances with different chemical properties. Examples of physical changes include melting ice or tearing paper, while examples of chemical changes include rusting of iron or burning wood.
What criteria are used to distinguish between a chemical and physical change?
One distinguishing feature between physical and chemical changes is that a physical change can be reverse or turn back to its original form, but chemical change cannot be return to its form because the material change.
What are physcial changes?
physcial change is is when something changing its form but it is still the same.
What is the differences between physical and chemical changes in relation to fire services?
Physical changes are melting and boiling in this case; fire is a combustion, a chemical change.
What are the differences between physical and chemical changes?
Physical changes involve a change in appearance or state of matter without altering the chemical composition, while chemical changes result in the formation of new substances with different chemical properties.
Differences between physical changes and chemical changes?
Physical changes are changes that affect the form of a chemical substance, such as changes in state or shape, without changing its chemical composition. Chemical changes, on the other hand, result in the formation of new substances with different chemical properties. Physical changes are usually reversible, while chemical changes are often irreversible.
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.
Are most chemical changes seen or not seen?
Most chemical changes happen between molecules, so they are unseen.

What is the differences between chemical and physical changes?
chemical- changes identity of substance. some signs: bubbles, precipitate forms, color change, difference in temperature physical- does not change identity of substance. can be homogeneous or heterogeneous. meaning appearing to be the same throughout and appearing to have different parts throughout; respectively.
What ARE the MAJOR and MINOR differences between the two software versions?
The major differences between the two software versions are significant changes in features, functionality, and user interface. Minor differences are smaller changes that may not have a big impact on overall usage.
Are chemical changes when substances combine or are they when substances breaking apart?
A reaction between two substances or the decomposition of a substance are chemical changes.
Write 3 differences between chemical and physical change?
Okay now here goes in a physical change no chemical reaction takes place. in chemical change chemical reactions take place. A physical change is reversible but a chemical change is not.In a physical change no new substance is formed(A+B=B) in a chemical change new substances are formed(A+B=C)
What are the similarities between chemical and physical changes?
Both chemical and physical changes involve a transformation of matter. In physical changes, the substance's chemical composition remains the same, while in chemical changes, new substances are formed as a result of a chemical reaction. Both types of changes involve the absorption or release of energy.
