In sublimation, iodine particles transition directly from a solid state to a gaseous state, which requires an input of energy. This energy increases the kinetic energy of the iodine particles, allowing them to overcome intermolecular forces and escape into the vapor phase. As a result, the energy of the iodine particles increases during sublimation, leading to a higher degree of molecular motion in the gaseous state.
What else can I help you with?
Explain why sublimation is regarded as a physical change but the slaking of lime is considered as a chemical change?
- Sublimation don't change the molecule; solid iodine or sublimated iodine are iodine. - Slaking of lime transform the calcium oxide in calcium hydroxide. A chemical change occur.
When Combined With Other Substances Do Iodine Particles Change Or Does The Arrangement Of Iodine Particles Change?
When combined with other substances, iodine particles can change through chemical reactions, forming new compounds or mixtures. The arrangement of iodine particles may also change depending on the nature of the interaction, such as forming ionic or covalent bonds with other elements. In some cases, the physical state of iodine (solid, liquid, or gas) can shift, affecting how the particles are organized. Overall, both the particles and their arrangement can change when iodine interacts with other substances.
When iodine particles is mixed with an amber solution does the particles or the arrangement change?
When iodine particles are mixed with an amber solution, the iodine may dissolve and change its arrangement at the molecular level, forming a homogeneous mixture. The iodine molecules disperse evenly throughout the solution, altering the visual appearance and potentially affecting the solution's properties. However, the iodine itself remains chemically unchanged during this process.
When iodine sublimes it absorbs energy?
When iodine sublimes, it transitions from a solid state directly to a gaseous state without passing through a liquid phase. This process requires energy, known as the enthalpy of sublimation, which is absorbed from the surroundings. As the iodine molecules gain energy, they overcome the intermolecular forces holding them together in the solid form, resulting in the formation of gaseous iodine. This absorption of energy leads to a cooling effect in the surrounding environment.
Is deposition of iodine a Physical or chemical change?
Deposition of iodine is a physical change. It involves the transition of iodine from a gas directly to a solid without passing through the liquid phase, which is a process called sublimation in reverse. Since the chemical identity of iodine remains unchanged during this process, it does not involve any chemical reactions or the formation of new substances.
Is iodine sublimating a chemical change?
Yes, the sublimation of iodine is a physical change, not a chemical change. Sublimation is the process by which a substance transitions from a solid directly to a gas without passing through the liquid phase. The chemical composition of iodine remains the same during sublimation.
The process by which iodine particles change directly to a gas without first becoming a liquid called?
it's called sublimation
Explain why sublimation is regarded as a physical change but the slaking of lime is considered as a chemical change?
- Sublimation don't change the molecule; solid iodine or sublimated iodine are iodine. - Slaking of lime transform the calcium oxide in calcium hydroxide. A chemical change occur.
Is sublimation of iodine a physical change?
Yes, the sublimation of iodine is a physical change. Sublimation is the process by which a substance transitions directly from a solid to a gas without passing through the liquid phase, and the chemical composition of the substance remains the same.
Is the heating of iodine crystals a chemical or physical change?
It is a physical change (sublimation).
Is sublimation of iodine represents a chemical change?
Yes, sublimation of iodine represents a physical change. Sublimation is the process where a substance transitions from a solid directly to a gas without passing through the liquid phase, and the chemical composition of the substance remains the same.
What chemical compound forms when you heat Iodine?
Heating iodine sublimation occur: this is a direct change from solid to gas.
Can iodine and naphthalene be separated by sublimation?
Yes, iodine and naphthalene can be separated by sublimation because they have different sublimation points. Iodine sublimes at a lower temperature compared to naphthalene, allowing for the selective separation of the two substances based on their sublimation properties.
Is sublimation of iodine reversible or irreversible?
it is a physical change , sublimation is a transition of a substance from the solid phase to the gas phase without passing through an intermediate liquid phase. the iodine crystals when subject to heat turns to a violet gas , and when it cools it turns back to solid form. the composition doesn't change so it n is only a physical change
Iodine sublimes to iodine vapor is physical or chemical change?
Sublimation of iodine to iodine vapor is a physical change. It is a phase transition in which a substance goes directly from a solid to a gas without changing its chemical composition.
When Combined With Other Substances Do Iodine Particles Change Or Does The Arrangement Of Iodine Particles Change?
When combined with other substances, iodine particles can change through chemical reactions, forming new compounds or mixtures. The arrangement of iodine particles may also change depending on the nature of the interaction, such as forming ionic or covalent bonds with other elements. In some cases, the physical state of iodine (solid, liquid, or gas) can shift, affecting how the particles are organized.

In what particles pass directly from solid to gas?
It is called sublimation
