<span>1)    </span><span>What is air pressure? (Answ</span>er: Atmospheric pressure, sometimes also called barometric pressure, is the pressure within the atmosphere of Earth.)

<span>2)    </span><span>What is a barometer and what is it used to measure? <span>(Answer: A barometer is a scientific instrument used in meteorology to measure atmospheric pressure. Pressure tendency can forecast short term changes in the weather.)</span></span>

<span>3)    </span><span>How does air pressure change?  <span>(Answer: Millibar values used in meteorology range from about 100 to 1050. At sea level, standard air pressure in millibars is 1013.2. Weather maps showing the pressure at the surface are drawn using millibars. ... This change in pressure is caused by changes in air density, and air density is related to temperature.)</span></span>

<span>4)    </span><span>Why is cooler, drier air related to High Pressure? <span>(Answer: This is due to density differences between the two air masses. Since stronger high-pressure systems contain cooler or drier air, the air mass is denser and flows towards areas that are warm or moist, which are in the vicinity of low pressure areas in advance of their associated cold fronts.)</span></span>

<span>5)    </span><span>Why is warm, moister air related to Low Pressure?  <span>(Answer: When air warms, its molecules scatter. The air becomes lighter and rises.)</span></span>

6.) The barometer would show a decrease in wind speed resulting in the dissipation of cloud cover because of the lack of wind, and also because the temperature is dropping there is less precipitation because there is no hot air rising to create clouds.

7.) If it is getting cloudy, it is because the air is rising. This is what causes the condensation of the moisture by adiabatic cooling of a lesser pressure aloft. If the air is rising, the pressure must fall. The barometer will show a lesser pressure. The temperature, on the other side, has very little to do with it.

Given the information you now know, what is the effect of hyperventilation on blood pH?pH? During hyperventilation, the rapid in
Ksju [112]

Answer:

When hypercapnia processes occur, where the concentration of carbon dioxide gas increases in the blood, the protonization of the blood increases, this means that the H + ions increase in concentration, thus generating metabolic acidosis.

This metabolic acidosis is regulated by various systems, but the respiratory system collaborates by generating hyperventilation, to increase blood oxygen pressures, decrease CO2 emissions, and indirectly decrease acidity.

Explanation:

This method of regulating the body is crucial, since the proteins in our body will not be altered if they do not happen.

The enzymes, the red globules, and many more fundamental things for life ARE PROTEINS, that in front of acidic media these modify their structure by denaturing themselves and ceasing to fulfill their functions. This is the reason why it seeks to neutralize the blood pH when it comes to an increase in CO2.

Describe the results of a physical change and list<br> three examples of physical change.
Alex Ar [27]

Physical changes are changes affecting the form of a chemical substance, but not its chemical composition. Physical changes are used to separate mixtures into their component compounds, but can not usually be used to separate compounds into chemical elements or simpler compounds.

Ex: cutting a paper, gaining weight, cutting hair

If the temperature of a gas confined to such a cylinder is raised from 287°C to 587°C, what is the ratio of the initial volume t
jenyasd209 [6]

Answer:

1 : 2

Explanation:

From the question given, we obtained the following information:

T1 = 287°C = 287 +273 = 560K

T1 = 587°C = 587 +273 =860K

V1 = V

V2 =?

V1 /T1 = V2 /T2

V/560 = V2/860

Cross multiply

V2 x 560 = 860 x V

Divide both side by 560

V2 = (860 x V) / 560

V2 = 1.54V = 2V

The ratio of initial to final volume =

V1 : V2

= V : 2V

= 1 : 2
