FALSE!!!!
Steam is still water (H2O), but in the form of very small droplets.
Liquid water to steam is a physical change.
What else can I help you with?
A substance that undergoes a chemical change is still the same substance after the change?

Changing water to ice is an example of a chemical change true or false?
I'd say no. Melting just changes the physical properties. Example: A rubber ball. If you melt a rubber ball it will still be rubber, just in a different form.
In examples of chemical changes the odor of sour milk indicates a chemical change has taken place true or false?
True. The souring of milk is a chemical change caused by the breakdown of lactose sugars into lactic acid by bacteria. The change in odor is a result of this chemical reaction.
Is changing the size and shape of pieces of wood a chemical change true or false?
False. Changing the size and shape of pieces of wood is a physical change, not a chemical change. A chemical change involves the alteration of the chemical composition of a substance, while a physical change only affects the physical properties of a substance.
Can Changing a subscript changes the formula of the compound true or false?
It not only can change but really DOES change the formula.Changing the subscript in a chemical formula changes the number of atoms to which the particular subscript belongs. Doing this will change the formula completely, making it representative of another substance completely.
Is it true are false that a physical change of a substance changes its chemical makeup?
true
A substance that undergoes a chemical change is still the same substance after the change?

Is it true that Physical changes are often accompanied by changes in color or odor?
No, a chemical change is usually accompanied by a change in color or odor. A physical change is a change that is the same substance before and after and usually accompanied by a change in state of matter (evaporation, condensation, melting, freezing, sublimating, etc).
In examples of chemical changes the odor of sour milk indicates a chemical change has taken place true or false?
True. The souring of milk is a chemical change caused by the breakdown of lactose sugars into lactic acid by bacteria. The change in odor is a result of this chemical reaction.
Figure of speech is the common meaning of words undergoes a decided change in meaning?
False.
Is a physical change what happens when chemical bonds break and new bonds form?
No, a physical change does not involve breaking or forming chemical bonds. It only involves changes in physical properties like size, shape, or state of matter. Chemical changes involve the breaking and forming of chemical bonds to create new substances.
Is this true or false in a chemical change other forms of energy cannot be changed to chemical energy?
False
Is changing the size and shape of pieces of wood a chemical change true or false?
False. Changing the size and shape of pieces of wood is a physical change, not a chemical change. A chemical change involves the alteration of the chemical composition of a substance, while a physical change only affects the physical properties of a substance.

Water can change from liquid to gas only through a chemical reaction true or false?
False. The change of water from liquid to gas is a physical process known as evaporation, not a chemical reaction. This process occurs when water molecules gain enough energy to overcome the forces holding them together in the liquid state.
Is the sun's energy is produced by physical and chemical changes in the interior?
False
