Is the melting of ice a chemical change or a physical change?
its both a chemical change and a physical change.
What is an example of a physical change in baking?
both, because the ingredients are undergoing both physical and chemical changes such as: Butter melting= physical change Egg whites hardening= chemical change both, because the ingredients are undergoing both physical and chemical changes such as: Butter melting= physical change Egg whites hardening= chemical change
Is the melting of an ice cube considered a physical change or chemical change Explain your reasoning?
The melting of an ice cube is considered both a physical change and a chemical change simply because a chemical change is something burning, so if the ice cube is cold and hot at the same time, it's both a physical change and a chemical change.
A change of occurs during both freezing and melting?
A change in temperature occurs during both freezing and melting. Freezing and melting are physical changes since the chemical contents of the matter do not change.
Are melting butter and melting ice cream are both physical change or chemical change?
They're both physical changes. Phase changes are always physical changes. Chemical changes only involve chemical reactions - a change in the identity of the substance. That's why phase changes are physical changes. Ice cream remains ice cream when it melts.
How is a burning candle both physical and chemical changes?
A burning candle involves both physical and chemical changes. The physical change is the melting of the wax, while the chemical change is the wax combining with oxygen in the air to produce heat, light, carbon dioxide, and water vapor.
Why ice melting a chemical change?
Ice melting is a physical change rather than a chemical change because the substance (water) remains the same at a molecular level. The process involves a change in state from solid to liquid due to the absorption of heat energy, with no alteration to the chemical composition of the material.
When ice melts you can tell it is a chemical change because?
The melting of ice is a physical not, not a chemical change. You can tell this because the chemical composition of ice and water are exactly the same, i.e. they are both H2O. Only the physical property has changed since one is a solid and one is a liquid.
Can matter undergo a phyical and chemical change at the same time?
Yes, matter can undergo both physical and chemical changes simultaneously. For example, when a candle burns, the wax undergoes both a physical change (melting) and a chemical change (combustion) at the same time.
Are melting ice and cutting paper both physical change?
Yes, cutting paper and melting ice are both physical changes because the ice can be refrozen and the paper is still paper.
Is heating a chemical or physical change?
Heating a substance can result in either a physical change or a chemical change. A physical change does not alter the substance's composition, such as melting or boiling, while a chemical change leads to the formation of new substances with different properties, such as burning or baking.
Why burning of candle is a physical and chemical change?
