Pressure and volume are inversely proportional according to Boyle's law. The graph should be linear with a negative slope.

Background research about water purification and filtration!!!
notka56 [123]

Answer: It's a modern-day engineering challenge to remove human-made contaminants from

drinking water. After a quick review of the treatment processes that municipal water

goes through before it comes from the tap you will learn about the still-present

measurable contamination of drinking water due to anthropogenic (human-made)

chemicals. Substances such as prescription medication, pesticides and hormones are

detected in the drinking water supplies of American and European metropolitan cities.

The engineering design process can be used to design solutions for a real-world

problem (contaminated water) that could affect health.

Engineering Connection

The water that comes from our faucets has passed through a complex system designed

by many different types of engineers. Civil, chemical, electrical, environmental,

geotechnical, hydraulic, structural and architectural engineers all play roles in the

design, development and implementation of municipalities' drinking water supplies and

delivery systems. Hydraulic engineers design systems that safely filter the water at a

rate needed to supply a specific region and population. Chemical engineers precisely

determine the amounts and types of chemicals added to source water for coagulation

and decontamination to make the water safe to drink and not taste bad. Even so,

modern pharmaceutical and agricultural practices persist in contaminating our water

supplies.

Who were the scientists who won the nobel prize for the atomic model?
AleksAgata [21]

Answer:

Here's what I find.  

Explanation:

Many scientists contributed to our model of the atom.

Among those who received the Nobel Prize for their work are:

1906 — J.J. Thomson        — discovery of the electron

1908 — Ernest Rutherford — nuclear model of the atom

1922 — Niels Bohr             — planetary model of the atom

1922 — Albert Einstein      — quantum mechanical model of the atom

1935 — James Chadwick  — discovery of the neutron

A minimumenergy of 7.21x10-19 J is required to produce the photoelectric effect in chromium metal.
forsale [732]

Answer:

<em>2.085 x 10^-20 J</em>

<em></em>

Explanation:

minimum energy required to produce photoelectric effect in chromium is given as hf =  7.21 x 10^-19 J

The work function of chromium Ф = 4.37 eV = 7.00151 x 10^-19 J

The minimum energy required to eject an electron from from a chromium metal E = ?

From E = hf - Ф

substituting values, we have

E = (7.21 x 10^-19) - (7.00151 x 10^-19)

E = <em>2.085 x 10^-20 J</em>

What is the melting point of stainless steel?
Mashcka [7]
<span>"Alloy additions also suppress (lower) the melting range. Pure iron (Fe) has a fixed melting point of 1535°C, chromium (Cr) 1890°C and nickel (Ni) 1453°C compared to a range of 1400-1450 °C for type 304 stainless steel."</span>

When aluminium and chlorine compared , which has smaller atomic size ? Why ?​
Zielflug [23.3K]
Chlorine has a smaller atomic size.
Explanation: As you move towards right of the periodic table, the atomic size decreases. This is because the number of protons is increasing towards the right of the periodic table, which applies a greater inward force on the electrons. that is why the elements on the right of the periodic table have a smaller atomic size when compared to the elements on the left. Since chlorine is on the right side of aluminium, it has a smaller atomic size.
