What else can I help you with?
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.
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.
True or false the temperature of a substance changes during a change in state?
False. The temperature of a substance remains constant during a change in state until all of the substance has completed the phase change.
Is a tree that is cut into boards at a sawmill a chemical change?
Sawing a board in half is not an example of chemical change. It is an example of a physical change. Physical changes on a substance do not change the substance. When you saw a board in half, the two halves of the boards are still boards- they're not anything else.
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.
Freezing is a change of state true or false?
Yes, freezing is change of state, from liquid to solid. Freezing is a physical change, not a chemical change.
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 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.
What is the breaking of a glass window is a physical change is true or false?
True.
When substances are mixed it can result in physical or a chemical change true or false?
true
Is it true are false that a physical change of a substance changes its chemical makeup?
true
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.
Which is A change in size shape or state of matter?
a change in size, shape or the state of matter is a physical change. True for A+.
True or false would the volume of water be the same before and after a physical change?
True
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.
Is it true when a physical change that takes new substances are formed?
No, in a physical change, no new substances are formed. The change only affects the physical appearance or state of the matter, such as size, shape, or phase, but the chemical composition remains the same.
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.
