It is a physical change called sublimation. Whereas most solids on being heated first become liquids and only vaporise (evaporate), i.e. turn into gas on heating to higher temperatures, there are some solids like sulphur or naphthalene (the material in moth balls) that directly go on heating from solid to gas, i.e. they sublime.
What else can I help you with?
Evaporation of alchohol is a chemical change ora physical change?
Evaporation of alcohol is a physical change.
Is the evaporation of water a potential sign of a chemical change?
No, evaporation causes a change in the state of matter (liquid to solid) which is a physical change
What is a physical change - corrosion explosion evaporation rotting of food?
Evaporation is a physical change: a change of state that is reversible.
Is evaporation a chemical property or a physical property?
Evaporation is a physical property. It is the process by which a substance transitions from a liquid state to a gaseous state without undergoing a chemical change.
Is water evaporating off the counter a physical or chemical change?
Evaporation is a physical change.
Is mothballs gradually vaporize in a closet a physical or chemical change?
The gradual vaporization of mothballs in a closet is a physical change. This is because the mothballs are changing from a solid state (solid mothballs) to a gaseous state (mothball vapor) without undergoing a chemical reaction.
Mothballs disappear over time is it a chemical change?
No, mothballs disappearing over time is a physical change, not a chemical change. The mothballs are still the same substance, just dispersed or evaporated into the air.
Is sublimation of mothballs physical or chemical change?
Sublimation of mothballs is a physical change. Sublimation is the process of a substance transitioning from a solid directly to a gas without going through a liquid phase. It does not involve a change in the chemical makeup of the substance.

What is a physical change - corrosion explosion evaporation rotting of food?
Evaporation is a physical change: a change of state that is reversible.
Is water evaporating into steam a chemical or physical change?
It is a physical change because the change is reversible.
Is evaporation physical or chemical change?
it is a physical change because it is not making a new substance. It is just changing the size/shape
Does evaporation cause a physical change or a chemical change?
It is physical change
Is evaporating a physical change?
Yes. Evaporation is a physical change of state. In the case of evaporation enough heat, called the Latent Heat of Vaporization, is added to a liquid to change it from liquid to gas.
