Examples of a physical change or a chemical change?
Physical changes can range from colour changes to change in tempricture.
Is melting ice a physical change or chemical change?
Physical; all phase changes are physical changes because the composition does not change.
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.
Are state changes physical or chemical changes?
State changes are physical changes because they involve a change in the physical properties of a substance, such as its form or state of matter (solid, liquid, gas). No new substances are formed during a state change, making it a physical change rather than a chemical change.
Are phrase changes a chemical or physical change?
Physical change
Are phase changes physical or chemical in nature?
Phase changes are physical changes in nature. They involve a change in the state of matter (solid, liquid, gas) rather than a change in the chemical composition of the substance. Heating or cooling a substance can trigger phase changes.
Are all physical changes accompanied by chemical changes?
Not all chemical changes are accompanied by a visible physical change. Most chemical changes however will be accompanied by a physical change.
Do physical changes involve change in energy?
Yes, physical changes involve a small change in energy.
Is a rusting bicycle a chemical changes or a physical change?
physical change
When a computer screen changes is it a physical or chemical change?
A physical change
Can matter change states after a physical change?
Yes, matter can change states after a physical change. Physical changes involve changes in the arrangement of particles without altering the chemical composition. For example, melting ice (solid to liquid) and boiling water (liquid to gas) are physical changes that involve changes in state.
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).
