Is White phosphorous ignites easily a physical change?
Yes, white phosphorus igniting is a physical change because it involves a change in the physical state of the substance (from solid to gas) without altering its chemical composition.
Is does not react with hydrogen a physical or chemical change?
This is a chemical property of an element. It indicates how an element interacts with other substances. In this case, the element does not undergo a chemical change when exposed to hydrogen.
Baking a cake is physical change or chemical change?
Baking a cake is a chemical change because the ingredients undergo a chemical reaction when exposed to heat, resulting in a transformation of their molecular structure to form the cake. This is different from a physical change, which does not alter the composition of the ingredients.
Is grilling a burger a chemical or physical change?
Grilling a burger is a chemical change because the proteins and fats in the meat undergo chemical reactions when exposed to heat, leading to the formation of new compounds that give the burger its characteristic flavor and color.
When you reuse a crystal heat pack is that a chemical or physical change?
Reusing a crystal heat pack involves a physical change. When the heat pack is exposed to heat or boiled to reset the crystals, the change is reversible and does not involve a chemical reaction.
Is turning of copper into green when exposed into environment physical or chemical change?
It is a chemical change.
Is the burning of phosphorus physical or chemical change?
Burning of anything is a chemical change. Combustion (burning) is a chemical reaction; it is simply where oxygen is added to, for example, an element, and turns it into an oxide. Burning phosphorus would result in phosphorus oxide. P + O2 --> P4010
Is White phosphorous ignites easily a physical change?
Yes, white phosphorus igniting is a physical change because it involves a change in the physical state of the substance (from solid to gas) without altering its chemical composition.
Does a physical or chemical change take place when an apple is exposed to oxygen over time with peroxide on it?
chemical

Is flamable a physical change?
No, flammability is a chemical property, not a physical change. Flammability refers to a substance's ability to undergo combustion when exposed to a flame or spark, which involves a chemical reaction where new substances are formed.
Is grilling a burger a chemical or physical change?
Grilling a burger is a chemical change because the proteins and fats in the meat undergo chemical reactions when exposed to heat, leading to the formation of new compounds that give the burger its characteristic flavor and color.

Reusing a crystal heat pack involves a physical change. When the heat pack is exposed to heat or boiled to reset the crystals, the change is reversible and does not involve a chemical reaction.
Is stapling an envelope a physical change or chemical?
A physical change
Lighting a match a physical change or chemical change?
Lighting a match is a chemical change because the molecules in the matchstick undergo a chemical reaction when exposed to heat, resulting in the production of new substances like ash and smoke.
Why does liquid nitrogen exposed to air is a physical change?
When liquid nitrogen is exposed to air, it rapidly evaporates and turns into nitrogen gas. This process is a physical change because only the physical state of the substance is changed from liquid to gas, without altering its chemical composition.
