States of Matter and Water (Chemistry)

Removal of water from a molecule - Dehydration, in a chemical context, refers to the process of removing water molecules from a substance. This can occur through various chemical reactions.

In the water cycle, snow and ice are directly converted into vapor. This process is called sublimation.

The process in which a solid substance on heating turns into a vapor without going into a liquid state and on cooling again becomes a solid without changing to a liquid state, is called sublimation.

The following are some subliminal substances- Ammonium Chloride, Iodine, Camphor Naphthalene, etc.

When a heavy component settles down after adding water to a mixture, this process is called 'sedimentation'. The components or particles that sit at the bottom during sedimentation are called 'sediment'.

The conduction method is used to separate two components of a mixture whose sizes are different. The process of separating grains or grains from the stems of dried plants is called Threshing.

Mercury is the only metallic element that is found in the liquid state at normal temperature and pressure (or room temperature). Aluminium, phosphorus, and sodium remain in a solid state at room temperature.

Mercury - As mentioned above, mercury is unique among metals in that it exists in a liquid state at normal room temperature. Bromite is not a metal, cadmium is a solid metal, and glass is an amorphous solid.

The atomic number of Gallium (Ga) is 31. It is soft and shiny in its pure state. It melts at normal temperature i.e. when kept on the palm. It is also used as semiconductor.

None of the above - While gallium melts in the palm, it is not listed as an option. Potassium and sodium are highly reactive alkali metals and are typically stored under oil to prevent reaction with air and water. Magnesium and aluminium have high melting points.

Waste water released from kitchen - Sullage water generally refers to wastewater generated from domestic activities such as washing, bathing, and food preparation in kitchens and bathrooms, excluding sewage from toilets.
