Why are subumation and deposition unusual changes of state?
Sublimation and deposition are unusual changes of state because they involve a direct transition between solid and gas phases without passing through the liquid phase. In sublimation, a solid absorbs energy and transforms directly into a gas, while in deposition, a gas releases energy and converts directly into a solid. These processes typically occur under specific temperature and pressure conditions and are less common compared to the more familiar changes of state like melting and freezing.
The process of turning a gas into a liquid?
The process of liquid heating and changing into vapor is called as vaporization. The particles in gas are moving faster compared to that of liquid so it needs a high input energy for the liquid to convert to gas.
Do areas near the equator experience more condensation and precipitation than areas near the poles?
Yes because the sun is very strong near the equator which means more evaporation happens. The more evaporation the more condensation. AKA the water cycle.
Which is the slow process evaporation or boiling?
Evaporation is very slow at converting liquid to gas compared to boiling.
What biogeochemical cycle is least dependent on biotic processes?
The water cycle is the least dependent on biotic processes because its main driving forces are evaporation, condensation, and precipitation, which are primarily driven by abiotic factors such as temperature and weather patterns. Biotic processes have a limited role in influencing the water cycle compared to other biogeochemical cycles.

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.

Yes because the sun is very strong near the equator which means more evaporation happens. The more evaporation the more condensation. AKA the water cycle.

Why do you separate a salt solution using boiling instead of evaporation?
Boiling is a faster process compared to evaporation for separating a salt solution because it increases the rate of evaporation. It also allows for the collection of the vapor and condensation back to recover the dissolved salt. Additionally, boiling can help to remove volatile impurities that may be present in the solution.
How wind affect rate of evaporation?
A strong warm wind will speed up evaporation giving us higher rates of evaporation in compared to a still cool day
Does the type of container affect the evaporation?
Yes, the type of container can affect evaporation. For example, a sealed container will slow down evaporation compared to an open container. Additionally, materials like glass or metal can also affect evaporation rates compared to porous materials like paper or cloth.
What is the difference between film and dropwise condensation?
Film condensation occurs when a continuous liquid film forms on a surface during the condensation process, while dropwise condensation occurs when discrete droplets form on the surface. Dropwise condensation is more efficient in heat transfer compared to film condensation due to reduced resistance to heat transfer at the liquid-vapor interface.
Why is boiling a faster process compared to evaporation?
Boiling occurs at a higher temperature and involves the entire liquid reaching its boiling point, whereas evaporation happens at the surface of the liquid. Boiling provides more energy to break the intermolecular forces holding the liquid molecules together, leading to a faster transition to the gas phase compared to evaporation.
What is the differences between sublimation and boiling?
Sublimation is the direct change of a substance from a solid to a gas without passing through the liquid phase, while boiling is the conversion of a liquid to a gas by heating the liquid to its boiling point. Sublimation typically occurs at lower temperatures and pressures compared to boiling.
