A substance undergoing a change in form only without any change in its chemical composition is known as a physical change. This can include changes in state (solid, liquid, gas) or shape without altering the fundamental properties of the substance. Examples include melting ice, boiling water, or bending a metal rod.

What adjectives describes physical change?
A physical change is when something changes from one state of matter (solid, liquid, or gas) without changing chemical composition. When ice melts or water freezes or evaporates, it remains H2O, so these are physical changes.
Why do tornadoes form by clouds?
Because only the the energy involved in a thunderstorm or developing thunderstorm is enough to form something as strong as a tornado.
What is the difference between chemical and physical changes?
Chemical changes involve the rearrangement of atoms to form new substances with different chemical properties. Physical changes, on the other hand, only affect the physical state of a substance (such as its shape, size, or phase) without changing its chemical composition.

That the energy of the universe is constant. It cannot be made or destroyed only converted into another form.Einstein made the connection between energy and mass with e=mc2Where c is the speed of light in a vacuum.Big bang theory states that at the dawn of time the energy of the universe was infinite, then 'something' caused an explosion and mass was created.
What is any change in matter that changes its physical form called?
A change in matter that changes its physical form is called a physical change. This type of change does not alter the chemical composition of the substance, but only its physical properties such as shape, size, or state (solid, liquid, gas).
What is the rate of change velocity called?
The rate of which something changes its velocity is the acceleration. A common mistake is to think that something moving fast is accelerating, but it's only accelerating if the velocity of that object is changing.

Is a change that alters the form of a substance without changing it into another substance is called what?
A change that alters the form of a substance without changing it into another substance is called a physical change. This type of change does not involve a change in the chemical composition of the substance, only its physical appearance. Examples include changes in state (solid to liquid) or changes in shape (cutting or crushing).
