The cuvet, solvent, and the other chemical species (other than the analytes) all absorb light. how do we compensate for this?

1)In your own words explain what air pollution is

Anna11 [10]

Explanation:

Question 1

Air pollution is the introduction of harmful gases and substances into the atmosphere that renders it unfit for use for life. Some of these toxic gases and particulates are:

Carbon monoxide
Carbon dioxide
Nitrogen oxides
Smoke
Dust particles
Soot

Question 2

Natural forms are the original nature or outlook of a substance. Examples of natural forms are:

Flowers
Leaves
Animals
Rocks
Shells
Corals

Question 3

Anthropogenic cause of pollution are human causes of pollution. Some of these are:

Combustion of fossil fuels in internal combustion engines release harmful and toxic gases into the atmosphere and causes hair pollution.
Improper disposal of waste can produce effluent that reaches the ground water system and other fresh water sources.
Noise pollution from airports is very harmful to ear.
Mining activities degrades soil and removes rich fertile soils that should be used for agriculture.
Mining wastes can lead to contamination of water bodies around.

Question 4

Fossil fuels are fuel types that forms from natural process in which organisms are decomposed anaerobically to preserve their energy components. Some of these fuels are:

Coal
Crude oil
Natural gas

Question 5

Heart diseases ; ischaemic heart diseases can lead to failure of the heart when it does not receive enough oxygen from the environment. Air pollution contaminates available oxygen in the atmosphere and this is very dangerous to life.
Lung cancer: poor air quality can lead to the development of cancerous tumor in the lungs.
Asthma: air pollution is one of the leading cause of asthma.

Other notable mentions are bronchitis, pulmonary diseases, stroke

Question 6

_7 million____ people die each year from air pollution according to the world health organization

Question 7

Air Quality Index(AQI) is an indicator used to express the quality of air in particular area. The AQI can tell the present air quality condition. It can also be used to forecast future air quality in years to come.

It shows how clean and polluted the air is.

Question 8

The air quality index uses different colors to alert people about the quality of air. Each color represents different health implication of air quality:

Attached image shows the different colors used to alert people of about the air quality.

Question 9

About 7 million people die annually as a result of air pollution
Beijing cough is new disease that emanates from the rising air pollution in Beijing
Asia has the fastest rising cases of air pollution problems.
The best way to reduce air pollution is by riding bicycles and walking more.

plzzzzz help ..........How do the processes of conduction, convection, and radiation help distribute energy on Earth?

kodGreya [7K]

ENERGY TRANSFER IN THE ATMOSPHERE:

Atmosphere surrounds the earth made up of different layers of gases such as Argon, Oxygen, Nitrogen, Exophere, Thermosphere, Mesophere, Stratosphere, Toposphere

The energy that drives the climate system comes from the Sun. When the Sun's energy reaches the Earth it is partially absorbed in different parts of the climate system. The absorbed energy is converted back to heat, which causes the Earth to warm up and makes it habitable. Solar radiation absorption is uneven in both space and time and this gives rise to the intricate pattern and seasonal variation of our climate. To understand the complex patterns of Earth's radiative heating we begin by exploring the relationship between Earth and the Sun throughout the year, learn about the physical laws governing radiative heat transfer, develop the concept of radiative balance, and explore the implications of all these for the Earth as a whole. We examine the relationship between solar radiation and the Earth's temperature, and study the role of the atmosphere and its constituents in that interaction, to develop an understanding of the topics such as the "seasonal cycle" and the "greenhouse effect".

The Sun and its energy.

The Sun is the star located at the center of our planetary system. It is composed mainly of hydrogen and helium. In the Sun's interior, a thermonuclear fusion reaction converts the hydrogen into helium releasing huge amounts of energy. The energy created by the fusion reaction is converted into thermal energy (heat) and raises the temperature of the Sun to levels that are about twenty times larger that of the Earth's surface. The solar heat energy travels through space in the form of electromagnetic waves enabling the transfer of heat through a process known as radiation.

Solar radiation occurs over a wide range of wavelengths. However, the energy of solar radiation is not divided evenly over all wavelengths but is rather sharply centered on the wavelength band of 0.2-2 micrometers (μm=one millionth of a meter).

The physics of radiative heat transfer.

Before proceeding to investigate the effect of solar radiation on Earth we should take a moment to review the physical laws governing the transfer of energy through radiation. In particular we should understand the following points:

The radiative heat transfer process is independent of the presence of matter. It can move heat even through empty space.

All bodies emit radiation and the wavelength (or frequency) and energy characteristics (or spectrum) of that radiation are determined solely by the body's temperature.

The energy flux drops as the square of distance from the radiating body.

Radiation goes through a transformation when it encounters other objects (solid, gas or liquid). That transformation depends on the physical properties of that object and it is through this transformation that radiation can transfer heat from the emitting body to the other objects.

Radiation transfer from Sun to Earth.

Properties of Solar radiation: The Sun is located at the center of our Solar System, at a distance of about 150 x 106 kilometers from Earth. With a surface temperature of 5780 K (degrees Kelvin = degrees C + 273.15), the energy flux at the surface of the Sun is approximately 63 x 106 W/m2. This radiative flux maximizes at a wavelength of about 0.5 μm.

Solar radiation on Earth: As the Sun's energy spreads through space its spectral characteristics do not change because space contains almost no interfering matter. However the energy flux drops monotonically as the square of the distance from the Sun. Thus, when the radiation reaches the outer limit of the Earth's atmosphere, several hundred kilometers over the Earth's surface, the radiative flux is approximately 1360 W/m2.

Describe the four structural roles of the skeletal system.<br> The Human SKELETAL SYSTEM

makkiz [27]

Answer:

1. Support

2. Protection

3. Movement

4. Supply & Storage

Explanation:

1. Support : It provides a framework to support the organs and tissues of the body.

2. Protection: It protects our internal organs. The skull protects the brain; the thorax (sternum, ribs and spine) protects the heart, lungs and other viscera (organs within the thorax).

3. Movement: It provides a framework for muscles to attach. Then when the muscles contract they pull on the bones of the skeleton, which act like levers to create movement.

4. Supply & Storage: The bones that make up the skeleton are a source of both red blood cells (which transport oxygen) and white blood cells (which fight infection), which are formed within the bone marrow.
