Naphthalene can sublimate at room temperature because it has a low vapor pressure, meaning it easily transitions from a solid to a gas without melting first. This process is driven by the molecules in the solid state having enough energy to overcome the intermolecular forces holding them together, allowing them to move directly into the gas phase.
What else can I help you with?
Is iodine a brittle solid at room temperature?
No, iodine is a dark purple, shiny solid at room temperature. It has a characteristic metallic luster and can sublimate directly from a solid to a gaseous state.
Which halogen is a grey solid?
Iodine is a grey solid halogen at room temperature. It has a shiny appearance and can sublimate into a purple vapor when heated.
What statement describes the phase change that when dry ice is placed in an open container at room temperature?
sublimation
How would you separate and purify constituents of mixture of salt of iodine?
To separate salt and iodine, you can use sublimation. The iodine will sublimate at room temperature, leaving the salt behind. To purify the iodine further, you can re-sublimate it by heating it gently and collecting the vapor to form pure iodine crystals.
Nitrous oxide is a sublime?
Nitrous oxide is actually a gas at room temperature and pressure. Sublimation is the process where a solid turns directly into a gas without becoming a liquid first.
Is carbon a liquid at room temperature?
No. Carbon is a solid at room temperature and will sublimate (go from solid straight to gas i.e. no liquid) at 3900 Kelvin.
Is iodine a brittle solid at room temperature?
No, iodine is a dark purple, shiny solid at room temperature. It has a characteristic metallic luster and can sublimate directly from a solid to a gaseous state.
Which halogen is a grey solid?
Iodine is a grey solid halogen at room temperature. It has a shiny appearance and can sublimate into a purple vapor when heated.
What is a sentence for sublimation?
The sublimation process involves the transition of a substance from a solid directly to a gas, without passing through the liquid state.
What statement describes the phase change that when dry ice is placed in an open container at room temperature?
sublimation
When a liquid changes into a gas by heating it and there is no temperature change it is said to?

Can boiled water sublimate at extremely cold temperature?
Yes, the sublimation is possible.
Nitrous oxide is a sublime?
Nitrous oxide is actually a gas at room temperature and pressure. Sublimation is the process where a solid turns directly into a gas without becoming a liquid first.
Which statement describes the phase change that occurs when dry ice is placed in an open container at room temperature?
The dry ice will sublimate, which means it will change from a solid directly to a gas without passing through the liquid state. This process occurs due to the low temperature of dry ice (-78.5°C) compared to room temperature, causing it to transition directly to carbon dioxide gas.
Does fluorine sublimate?
Yes, fluorine can sublimate under certain conditions. Sublimation is the process in which a substance transitions directly from a solid to a gas phase without going through a liquid phase. At room temperature and pressure, fluorine generally exists as a gas, but at very low temperatures, around -188 degrees Celsius, it can be deposited as a solid and then sublimate back into a gas upon warming.
Is Iodine a solid liquid or gas?
AnswerIodine is an element that is a shiny grey solid and can be seen subliming slightly at RTP (Room Temperature and Pressure) into a purple-pink gas. Unless in solution, it is never a liquid.
