Tornadoes form when updrafts from thunderstorms begin to interact with strong wind shear and develop a rotating column of air.

Updrafts are powerful vertical currents of air that occur within thunderstorms, caused by the rapid heating of the Earth's surface and the subsequent convective process. These updrafts carry warm, moist air upward, creating a conducive environment for the formation of severe weather phenomena.

When the updrafts encounter wind shear, which is the change in wind speed and direction with height, it can lead to the development of horizontal vorticity. Wind shear creates a rotating motion within the storm, where air at different heights starts to rotate at different speeds, generating a horizontal spin.

As the updraft continues to intensify, it tilts the rotating column of air from horizontal to vertical, forming a mesocyclone. The mesocyclone is a critical component in tornado formation. It acts as a localized area of strong rotation within the storm, extending from the cloud base to the mid-levels of the atmosphere.

Under specific conditions, such as the presence of a strong updraft, a well-developed mesocyclone, and further enhancement from other atmospheric factors, the mesocyclone can contract and intensify into a tornado. The process is complex and influenced by various meteorological factors, but the interaction between updrafts, wind shear, and the development of rotation plays a fundamental role in tornado formation.

A disadvantage of disposing of waste polymers through recycling is that

they must first be separated.

Recycling is the process of forming new polymers and compounds as against their disposal .

Recycling involves separating the items into various sections such as paper,

plastic , metal etc. This is because they both undergo different recycling

processes.

The disadvantage of this process is that it's time consuming and also

expensive as a great amount of time and man power is needed to

separate the waste items.

Chemical energy

Explanation:

I hope this helped you!

Batteries store the energy in the form of chemical energy that chemical energy is converted into electrical energy. Chemical energy is used to stored in the substances within battery.

The conversion of chemical energy into electrical energy or vice versa is called as electrochemical energy . This includes reactions transferring electrons, redox reactions .

Redox reaction in which reduction and oxidation takes place simultaneously. Reduction, when a substance receives one electron. Oxidation when a substance gives away one electron.

A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit.

Thus, chemical energy is used to store in the substance within battery.

(a) The work done by the nitrogen against external pressure is 126.66 J.

(b) The change in the internal energy of the system is -2,466.66 J.

The given parameters:

The molar mass of the given compound is calculated as follows;

NaN₃ = 23+ (14 x 3) = 65 g/mol

65 g -------------- 42

2.25 g ------------- ?

[tex]= \frac{2.25 \times 42}{65} \\\\= 1.45 \ g[/tex]

The volume of the nitrogen gas is calculated as follows;

[tex]\rho = \frac{m}{V} \\\\V = \frac{m}{\rho} \\\\V = \frac{1.45}{1.165} \\\\V = 1.25 \ L[/tex]

[tex]V = 0.00125 \ m^3[/tex]

The work done by the nitrogen against external pressure is calculated as follows;

[tex]W = PV\\\\W = 101325 \times 0.00125\\\\W = 126.66 \ J[/tex]

The change in the internal energy of the system is calculated by applying first law of thermodynamics as follows;

The electrons start to repel each other.

Explanation:

Most atoms attain a lower potential energy when they are bonded to other atoms than when they are separated. One is that the single electrons that each hydrogen atom possesses begin to repel each other. This repulsive force would tend to make the potential energy of the system increase.

Answer: Place a piece of white paper under the analyte flask throughout the titration

Explanation:

The end point of titration can be made easy by the use of indicators. But we have to be keenly observe for each drop from the burette because, the colour change will be sudden for a drop.

Titration is an analytical technique used to determine the unknown concentration using a standard reagent of known concentration. The standard reagent of known concentration is called titrant and the  one to be determined is called analyte.

Usually analyte is taken in a conical flask and titrant in a burette. The end point of titration is the point at which the reaction is completed in perfect stoichiometry.

In acid-base titrations, the indicators used having different colors in different pH. Hence, the indicator in the analyte will change in color when the acidity of the medium changes. We have to observe keenly for the color change because it happens for any drop.

The adding of titrant from the burette must be dropwise and thus we can get a time to notice the sudden colour change of indicator.
