Its because of the bonds between molecules or atoms breakng or forming. For instance when a solid is formed bonds are made between the molecules of the substance creating a rigid structure, if these bonds were broken then the substance would be able to flow like a liquid.

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.
How can you tell if a change of state has occurred?
A change of state occurs when a substance transitions from one state of matter (solid, liquid, gas) to another. You can tell if a change of state has occurred by observing changes in physical properties such as color, texture, temperature, or volume of the substance. Additionally, the substance may undergo a phase transition, like melting, freezing, boiling, or condensing.
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
Do freezing forms a new substance?
No. Freezing represents a physical change from the liquid to the solid state. The composition of the substance does not change.
What are the changes do materials undergo in physical change?
In a physical change, materials undergo a change in their physical state or appearance without changing their chemical composition. This can include changes in shape, size, phase (solid, liquid, gas), or state (melting, freezing, evaporating). Physical changes are usually reversible.
Is reactivity a physical change?
Reactivity is a chemical property, not a physical change. It refers to the ability of a substance to undergo a chemical reaction with another substance. Physical changes involve alterations in the form or state of a substance without changing its chemical composition.
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.
A physical change occurs when what?
A physical change occurs when a substance changes its physical form or state without changing its chemical composition. Examples include changes in size, shape, or state of matter (solid, liquid, gas).
Is State chemical or physical?
A physical state is physical and not chemical Physical Property is observed without changing a substance into another substance. Chemical property is the ability of a substance to change into different substance.
How can you tell if a change of state has occurred?
A change of state occurs when a substance transitions from one state of matter (solid, liquid, gas) to another. You can tell if a change of state has occurred by observing changes in physical properties such as color, texture, temperature, or volume of the substance. Additionally, the substance may undergo a phase transition, like melting, freezing, boiling, or condensing.
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 from any state of matter to another is called a?
This is called a change in the physical state of the substance. For example formation of ice from water is a change in the physical state of water.
What is the change of a substance from one physical state to another?
change of state
A change in state withought forming a substance?
physical change
What does a substance change in a physical change?
One possibility is a change in state.
What is the change of a substance from one physical change to another?
change of state
Does a physical change make the substance that undergoes it a different substance if not then what can change?
After a physical change a substance does not change its chemical composition it simply changes its state as, water to ice or vapours.
