Is toasting bread a physical or chemical change?
It is a chemical change because some compounds from bread are thermally decomposed.
Is mixing flour and yeast a physical or chemical change?
This is a chemical change because it has all the characteristics of one. The color changes, the texture changes, new stuff is created, and you can't separate by physical means. It is chemical.
Can a chemical change be undone?
Some chemical changes are reversible, others are not.
What are characteristics that describe the ability of a substance to form a new substance?
Chemical change or chemical reaction describes how a substance can form a new substance.
What are some characteristics of chemical change?

What are some Chemical reactions with more than 1 characteristics in common?
One example is- H2 + o2 + heat = h2o It is showing 2 characteristics, change in temperature and change in state
How would you determine if a chemical change had occurred?
Some characteristics of a chemical change are: - change of smell - change of color - release of gases - change of temperature - formation of a precipitate - change of the aspect - change of pH in solutions - change of viscosity - flames or explosion etc.
What is the differences between chemical and physical change?
A chemical change involves a change in a substance's chemical properties (characteristics that describe how it interacts with other substances).A physical change involves a change in a substance's physical properties(characteristics that describe certain features one can see with their 5 senses).
What are characteristics of a chemical change when you mix solids and liquids?
Some indicators of a chemical reaction are:- change of color- change of odor- release of a gas- change of the temperature- change of the viscosity- formation of a precipitate- change of general appearance- possible explosion- possible chemiluminescence -formation of new compounds
Is sand and dirt mixed a chemical or physical characteristics?
it is a physical change
When do you say that a change is chemical?
A chemical change has occurred when a new substance is formed. Characteristics of this include a color change, precipitate is formed or it bubbles meaning a gas has formed.
Is putting color to icing chemical or physical change?
Coloring causes only a physical change to icing because it does not alter the chemical characteristics of the icing.
What clues can you use to identify a chemical change?
Characteristics of a chemical change can include a temperature change, a color change, the production of bubbles, the production of a precipitate, and a smell.
What are characteristics do all chemical changes have?
All chemical reactions cause the change of color and the Change in temperature. Chemical reactions also have the characteristic of releasing gas.

What are the characteristic of physical change?
Some common characteristics of physical changes are change in texture, change in shape, and change in state. There can also be a change in temperature and a change in color, but these are also common characteristics of chemical changes. A physical change does not change the composition of the original substance.
