What is iodine crystals sublime to make purple gas physical or chemical change?
The sublimation of iodine crystals to produce purple gas is a physical change. This is because the change in state from solid to gas does not involve a change in the chemical composition of the substance. The purple color of the gas is due to the absorption and emission of specific wavelengths of light by the iodine atoms.
Is solid iodine sublimes into purple vapor a physical or chemical change?
Sublimation of solid iodine into purple vapor is a physical change because the chemical composition of iodine remains the same throughout the process. Only the physical state changes from solid to gas.
Is ice melting at 0 degrees Celsius a chemical property?
No, the process of ice melting at 0 degrees Celsius is a physical change, not a chemical property. It involves a phase change from a solid to a liquid state without any change in the chemical composition of the ice.
Is scrubbing the floor a physical or chemical change?
Scrubbing the floor is a physical change because the appearance or state of the floor is altered without changing the chemical composition of the materials involved.
Is color change a physical or chemical change?
It depends. In most cases, it is a chemical change as the different colored species have different chemical structures. However, it is possible to change color by very finely dividing particles of matter and this is a physical change.
Is purple color a physical and chemical change?
No, the color purple is a physical property of an object that results from the absorption and reflection of certain wavelengths of light. It is not the result of a physical or chemical change, but rather the interaction of light with the object's molecules.
Is black crystals of iodine turning into purple vapour of iodine a physical change or a chemical change?
The transformation of black crystals of iodine into purple vapor of iodine is a physical change. This is because the change does not involve a change in the chemical composition of iodine; it only involves a change in the physical state from solid to gas.
What is iodine crystals sublime to make purple gas physical or chemical change?
The sublimation of iodine crystals to produce purple gas is a physical change. This is because the change in state from solid to gas does not involve a change in the chemical composition of the substance. The purple color of the gas is due to the absorption and emission of specific wavelengths of light by the iodine atoms.
When iodinebecome to purple gas describe chemical properties?
Iodine sublimes into a purple gas without passing through a liquid phase. This is a change in physical state, which is a physical change.
Is solid iodine sublimes into purple vapor a physical or chemical change?
Sublimation of solid iodine into purple vapor is a physical change because the chemical composition of iodine remains the same throughout the process. Only the physical state changes from solid to gas.
Is iodine becomes a purple gas a chemical change?
Yes, iodine becoming a purple gas is a physical change, not a chemical change. A chemical change involves the formation of new substances with different chemical properties, whereas in this case, the iodine is just changing its physical state from solid to gas without forming any new substances.
Is stapling an envelope a physical change or chemical?
A physical change
If paper is shredded into confetti is that a physical or chemical change?
Physical. You're not actually changing the makeup of the substance, just the way it appears.
Is bread breaking a physical or chemical change?
Physical
Is a change of liquid to liquid a chemical change or physical change?
A change from one liquid to another is typically considered a physical change rather than a chemical change. This is because the chemical composition of the substances involved remains the same during the transition.
Is painting a door a physical or chemical change?
Physical change of the paint, not the door.
Is peeling an apple a physical or chemical change?
it is a chemical change
