What kind of change happens when the composition of a substance does not change?
A physical change occurs when the composition of a substance does not change. This means the substance retains its chemical identity but may undergo a change in its physical properties like shape, size, or state of matter. Examples include melting, freezing, boiling, or dissolving.
What happens to a substance in physical change?
it means figure it out yourself!
What is the meaning of Physical Change What is the meaning of Chemical Change?
PHYSICAL CHANGE - refers to the change in size, shape, or state of matter. CHEMICAL CHANGE - happens when one chemical substance is transformed into one or more different substance, such as iron becomes rust.
Is it a physical or chemical change when a substance changes form but it remains the same substance?
it would be physical change because physical change is when the substance stays the same
When a substance changes into a different substance a blank change has occurred?
If form changes but identity doesn't change then it is a physical change.
How is the thermal energy of a substance related to it physical state?
The thermal energy of a substance determines its state, since thermal energy, aka internal energy, is the energy the molecules in the substance have. If the energy exceeds the force holding the substance together the substance undergoes a phase change.The physical state of a substance is related to its temperature, the measure of thermal energy. The substance can change states depending on the temperature, e.g. boiling.
What happens when you take the heat away from a substance?
Physical change
What kind of change happens when a substance dissolves?
I want to say physical change
What happens When a substance goes through a physical change?
The Substances die

What happens to energy during a change of state why is it a physical change?
Its released or adsorbed. Its "physical" because no new substance(s) is produced.
Is thermal expansion and contraction a physical change?
Yes, thermal expansion and contraction are physical changes. They result from the change in temperature of a material, causing its molecules to either spread out (expansion) or come closer together (contraction), without altering the chemical composition of the substance.
How is a physical change related to a substance physical property?
a physical change is a change in any physical property of a substance, not in the substance itself

What happens to the atom or molecules of a substance if it melts?
Nothing. Melting is a physical change and does not alter the chemical composition of a substance.
