Examine the molecules below.

Circle the molecules that can also be classified as compounds.

Answer:

solid

Explanation:

because solid has a definite shape and volume

Answer:

Liquid

Explanation:

This is because the intermolecular forces of attraction are strong enough to hold the molecules together but not so strong as to fix them into definite positions (as in solids). Instead, they possess fluidity and hence no definite shape.

Answer:

cellular respiration

Explanation:

Summary. Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body's cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP

styrofoam: 14 degrees

metal: 55 degrees

paper: 25 degrees

plastic: 28 degrees

if they are asking for temperature change, just subtract the last number from the first number to get the difference :)

Answer:

styrofoam would be 14°

metal would be 55°

paper would be 25°

plastic would be 28°

Explanation:

im pretty sure you just take the biggest number and subtract the smallest number. to get how much it has changed.

Explanation:

[tex]pressure \: \alpha \frac{1}{volume} [/tex]

P1V1 = P2V2

205 (4) = P2 (12)

[tex]P2 = \frac{205 \times 4}{12} [/tex]

P2= 820/12

P2= 68.3 KPa

The pressure in the container after the expanssion of gas, if the temperature remains constant is 68.3 kPa.

According to the Boyle's Law, at constant temperature pressure of any gas is inversely proportional to the volume of the gas, i.e.

P ∝ 1/V

Required equation for the calculation of the pressure is:

P₁V₁ = P₂V₂, where

P₁ = initial pressure = 205 kPa

V₁ = initial volume = 4 L

P₂ = final pressure = ?

V₂ = final volume = 12 L

On putting all these values on the above equation, we get

P₂ = (205)(4) / (12) = 68.3 kPa

Hence resultant pressure is 68.3 kPa.

creating geographic maps of continents and countries

Jonah is filling out paperwork for insurance and in the “applicant occupation” space he writes cartographer so, his job is creating geographic maps of continents and countries, hence option C is correct.

A person who draw and produce a map is a cartographer. Cartography is  the art and science of graphically representing a geographical area, usually on a flat surface such as a map or chart.

This may involve the superimposition of political, cultural, or other nongeographical divisions onto the representation of a geographical area.

A person whose work is making maps or charts is a cartographer.   An example of a cartographer is Claudius Ptolemy and his book Geographica . Anaximander was the first  ancient Greeks to draw the map of known world.

Hence, cartographer creates the geographical maps.

It is important for scientists to have a standard system of naming compounds and other chemical procedures to avoid ambiguity in the nomenclature of chemical compounds and procedures.

Chemicals may be referred to by various names among various scientists in different places. These different names creates confusion when scientists present their discoveries to other scientists outside their locality.

Therefore, it is imperative that a unified and standard system of nomenclature should be devised so that all scientists can have the same name for compounds. This reduces ambiguity associated with the nomenclature of chemical substances and procedure.

The  Great Fire of 1910 that burned through parts of North Idaho, western Montana, eastern Washington, and southeastern British Columbia serves as a model of conduction as the fire spread from tree to tree without actual movement of the trees away from their position but as a result of contact between the burning flames in the trees.

Heat transfer processes refers to the process by which heat energy is transferred from one point to another within a medium of between two points.

There are three processes of heat transfer, namely:

Conduction is a process of heat transfer in which is transferred from one point to another in a medium without the actual movement of the particles of that medium.

During conduction, the particles of the medium vibrate about a mean position as they acquire heat. This heat energy is then transferred from that particle to the neighboring particle as they particles are in close contact. Hence the heat is transferred from one particle to the next.
