What conditions does physical change occur in materials?
Physical changes in materials occur when the material undergoes a change in its physical properties without any change in its chemical composition. Examples of conditions that can cause physical changes include changes in temperature, pressure, or exposure to light or electricity. Physical changes can include changes in state (such as melting or freezing), changes in shape or size, or changes in properties (such as conductivity or solubility).
Are all physical changes reversible with examples?
Not all physical changes are reversible because most times when such changes occur parts of the substance is lost to the environment.
What is always involved when physical or chemical changes occur in matter?
When physical changes occur in matter, the substance's state or appearance changes without altering its chemical composition. In contrast, chemical changes involve a modification in the substance's chemical composition, resulting in the formation of new substances.
Which occurs more often on earth physical changes or chemical changes?
Physical changes occur more often on Earth compared to chemical changes. Physical changes involve alterations in the state or appearance of matter without changing its chemical composition. Examples include changes in shape, size, or state of matter (solid, liquid, gas). Chemical changes involve the formation of new substances with different chemical properties.
Why cutting of tree branches is physical change?
Because any chemical changes occur.
