A gas can't turn directly into a solid but a solid can turn into gas for example ice to water vapor.
It is called sublimation when you turn a solid into a gas. When you turn a gas into a solid it is called deposition.
To turn a liquid into a solid you have to freeze it. To turn a gas into a solid you must first turn it into a liquid, then freeze it.
Water is water, whether solid (ice), liquid or gas.
Turning a solid to a gas is sublimation. You cannot go directly from a gas to a solid. First you have to condense the gas and then freeze it. Sure you can - at the triple point
After the iodine is in gaseous form, contain and cap it off with an iced container to recollect it and turn it back into a solid by allowing the gas to rest. The temperature then has to be below 113.5°C in order to solidify.
All matter can turn into solid, liquid, gas, or plasma form.
sublimation!!
I turns into a gas not a solid because the only way you can make it a solid is by freezing it and this is applying heat
