They are the same substance, just in a different state. Ex: water>ice>water vapor is still water.
What else can I help you with?
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.
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+.
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.
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 physical and mechanical change the same as physical and chemical change?
no its not true
Is it true that a physical change and a chemical are exactly alike?
Not true, they are not similar; a chemical change is a change in the molecule, the physical change is not.
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.
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.
Which of the following is true about a physical change in matter?
It is something that can be seen, touched, tasted, smelled, or observed in some way.
What is the breaking of a glass window is a physical change is true or false?
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.
Is it true are false that a physical change of a substance changes its chemical makeup?
true
