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).
