Explanation:

Conduction is a form of heat transfer between one body and another. It usually occurs when a warmer object is in contact with a cooler one. Heat generally flows from a region of high temperature to a place at a lower temperature.

Conduction is very pronounced in solid bodies.
The heat transfer causes a net transfer of the average kinetic energy of one body to the other.
Some examples are: heating of iron by a hotter metallic body, the pot hand getting hotter as cooking continues, cooling of ice by touching it.

Draw the structures of the two monomers that react together to form this polyurethane polymer

matrenka [14]

The monomers that react together to form polyurethane polymer are diisocyanate and diol.

<h3>What are polymers?</h3>

Polymers are a class of natural or synthetic substances
It is made up of small units called monomers arranged in a repeated pattern to form large molecules called macromolecules
Cellulose and resins are examples of natural polymers
Polyethylene and polychloroprene are examples of synthetic polymers.

Polyurethane polymer is made up of monomers diisocyanate and diol. It is mostly used in home furnishing in flexible form. The structures of monomers are as follows:

What is the lowest numbered energy level where a d sublevel is found?

UkoKoshka [18]

Answer : The lowest numbered energy level where a 'd' sublevel is found is 3.

Explanation : According to the theory of order of electron filling;

The 4s orbitals is observed to have a lower energy than the 3d, and so the 4s orbitals are filled first.

It is known that 4s electrons are lost first during ionisation activity. Therefore, the electrons lost first will come from the highest energy level, furthest from the influence of the nucleus.

So, the lowest energy level where 'd' sub shell will be found is 3d.
