Is iodine melting a chemical or physical change?
Iodine melting is a physical change, as it does not alter the chemical composition of the iodine. It simply changes from a solid to a liquid state due to the input of heat energy.
What is iodine's physical state at 20 degrees C?
Iodine is a solid at 20 degrees Celsius.
Is iodine a physical property or a chemical property?
Iodine itself is a chemical element with a physical property, as it is a solid at room temperature and has a distinctive purple color. Its chemical properties involve its reactivity with other elements and compounds in chemical reactions.
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 colour is the iodine in the bottle?
The color of iodine in the bottle is typically purple or brown.
What is the physical state of iodine when it is at 250 celcius?
Iodine is in gaseous state at 250 degrees Celsius.
What is the physical state of iodine at 21 degrees?
gas

What is iodine's physical state at 20 degrees C?
Iodine is a solid at 20 degrees Celsius.
Purple iodine vapor appears when solid iodine is warmed is that chemical or physical change?
It is a physical change because the iodine is changing state from solid to gas without forming any new substances.
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 a physical property or a chemical property?

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 the physical state of iodine at freezing point?
Frozen. Any frozen substance is, by definition, solid.
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.
What is yellow brown colour?
Iodine
What colour is the iodine in the bottle?
The color of iodine in the bottle is typically purple or brown.
