Explanation

Sublimation is the process in which water vapour directly condenses into solid form.

Condensation is the process of transformation of water vapour into water.

Evaporation is process by which water or a liquid is transformed from liquid to gaseous state.

Precipitation is the condensation of water vapor in air in form of water droplets or ice.

Explanation

Stainless steel is a alloys that contain a minimum of approximately 11% chromium, a composition that prevents the iron from rusting and also provides heat-resistant properties.

Explanation

Symbol of mercury: Hg

Atomic number: 80

Boiling Point: 356.7 C

Explanation

Steel is an alloy of iron (Fe) and carbon (C), with small amounts of other elements like manganese, chromium, and vanadium.

It's a mixture of two or more elements, where at least one is a metal, making it an alloy.

Explanation

• An alloy of Cu - Sn is called Bell metal.
• Bell metal is a specific type of bronze with a higher tin content, commonly used for making bells.

Explanation

 Hematite is an ore of iron

It is one of the most abundant minerals on Earth's surface.

It is a common rock-forming mineral

That is found at locations throughout the world in:

• sedimentary rocks
• metamorphic rocks
• igneous rocks 

Explanation

Brass is an alloy of Zinc and Copper.

Explanation

• If we consider the time between melting point and boiling point, then we get the liquid state of the substance.

Explanation

Metalloids are known to have electronic band structures that are similar to semimetals or semiconductors.

Metalloids are known to form amphoteric or weakly acidic oxides.

These elements have the ability to form metallic alloys.

Explanation

Dry ice (solid carbon dioxide) is an example of a solid that undergoes sublimation.

Camphor, naphthalene, and ammonium chloride are sublime materials.
