It doesn't take much encouragement at all...just stick the dry ice somewhere that's warmer than -100 degrees F and it'll do it all by itself.

Is a dry ice evaporating a physical change?
Of course. If you can change the solid to a gas you can turn the gas into a liquid then you can change the liquid into a solid. It is called changes of matter.
Does dry ice go through a physical change or chemical change?
It is a physical change (phase change). Dry Ice is frozen carbon dioxide gas. At atmospheric pressure, liquid CO2 is unstable. So the frozen solid "sublimes" turning directly from a solid to a gas (absorbing heat from around it).
Changing state from solid to gas?
Dry ice can change from solid to gas without liquid state. When this occurs it is called 'to sublime'
When a solid change directly into a gas it what?
Sublimation. Example: Dry ice turning into carbon dioxide
Do gas particles become larger when dry ice changes into carbon dioxide?
The particles change from being tightly held in a solid to being free in the form of a gas; the molecules do not change size.
Is dry ice subliming a physical change?
It is a physical change because even though it is a gas, it can be made back into what it used to be. Just like ice melts into water and water heats and evaporates to gas. Water can easily be frozen back to ice. Gas can turn back to water. Dry ice sublimating is a physical change of carbon dioxide between a solid state and a gaseous state without going through a liquid state. If it were s chemical change, than it would no longer be carbon dioxide after changing state.
Why does dry HCl gas does not change the colour of the dry litmus paper?
Hydrogen chloride gas is not an acid, is not in solution and does not donate protons. So, no litmus paper color change.
Can a solid change into gas?
Yes. Dry ice, for example.
Is a piece of dry ice changing into a gas a physical change?
Yes
What is the changing state of phase?
The change of phase or state is when a liquid, gas, or solid change its form! liquid can turn into a solid (ice) or a gas (steam). Gas can turn into a liquid (water).But there are some exceptions to this rule , such as dry ice. Dry ice turns directly into a gas.
Is a dry ice evaporating a physical change?
Of course. If you can change the solid to a gas you can turn the gas into a liquid then you can change the liquid into a solid. It is called changes of matter.
Why does dry HCl gas not change the colour of the dry litmus paper?
Litmus paper tests the acidity or baseness of liquids.
What is added to dry ice to make it change?
Essentially, dry ice will simply change from a solid straight to a gas through sublimation at room temperature. Nothing is needed to change the state of matter of dry ice except a higher temperature.

What is the process that change a liquid back to a gas?
condensation
