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.
In physical change matter cannot change its shape true or false?
False. In a physical change, matter can change its shape without changing its chemical composition. Examples include melting, freezing, and dissolving.
True or false a physical change occurs when matter changes state as form a liqued to a gas?
True. A physical change occurs when matter changes state without altering its chemical composition. In this case, the change from a liquid to a gas involves only changes in physical properties such as volume, shape, and density.
Does a temperature change indicate a physical change?
Yes, it is possible.
Is it true or false for A Change In State Is A Physical Change?
True. A change in state, such as from solid to liquid or gas, is a physical change because the substance's chemical composition remains the same and only its physical properties, like shape or state, change.
During a chemical change the form of a substance is altered but not its identity true or false?
The statement is false: A chemical change of a substance is defined as a change in which the substance is not the same substance after the change as it was before.
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 a physical changethe makeup matter is changed true or false?
False. In a physical change, the makeup of matter remains the same, only the physical properties like shape, size, or state are altered. No new substances are formed during a physical change.
True or false the dissolving of sugar in water is an example of a chemial change?
false - it's a physical change. The sugar remains sugar only in solution.
When water changes to steam it undergoes a chemical change true or false?
False. When water changes to steam, it undergoes a physical change, not a chemical change. Heating water to its boiling point causes it to change from a liquid to a gas, but the chemical composition of water (H2O) remains the same.
What is the breaking of a glass window is a physical change is true or false?
True.
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).
