Answer:

The region just above the light bulb is warmest due to the phenomenon of convection.

Explanation:

In the given case, as Xavier places his hands close to a light bulb, he feels that some of the regions around the light bulb are warmer in comparison to others. This takes place due to the phenomenon known as convection because of which the region directly above the light bulb gets warmest in comparison to the other regions.  

Convection refers to the transfer of heat with the help of mass movement of fluid like air, and the phenomenon takes place above a hot surface as hot air expands, becomes less dense, and elevates. This thing can be supported by the ideal gas law.

Metallic bonds are responsible for many properties of metals such as conductivity true or false?.
Alex17521 [72]

It is true that metallic bonds are responsible for many properties of metals such as conductivity.

Metallic bond is a type of chemical bond.

Metallic bond is formed between electrons and positively charged metal ions.

Substances with metallic bond conduct an electric current in liquid and solid state, because they have mobile electrons.

Most metals (for example sodium, calcium, iron, silver) have strong metallic bond, because strong electrostatic attractive force between valence electrons (metals usually have low ionization energy and lose electrons easy) and positively charged metal ions.

Metallic bond increace electrical and thermal conductivity.
