Answer:
beneath the surface of Earth
Explanation:
Diamonds are made up of carbon that has been placed under extreme heat and pressure conditions.
These conditions of high pressure and temperature can only be found within the subsurface. As you go deeper to the mantle, the geothermal gradient rises significantly.
Also, the overburden pressure will also be high.
These processes can also occur on other planets and some can be associated to the earth times when the earth was being formed.
The condition at which diamond forms confers some of the distinct natural properties that typifies it.

In what way does the shape of a molecule affect how the molecule is
involved with living systems?
OA. It determines the weight of the molecule.
OB. It determines how the molecule functions.
O C. It determines oxidation states present in the molecule.
OD. It determines what elements are in the molecule.
Answer:
B
Explanation:
I'm not 100% sure, but B seems like the most likely answer because the shape of a molecule usually is a major factor in how molecules interact with each other.
I hope that helps.
Which energy transformation produces electricity and is least likely to negatively impact the environment?
A) Generating electricity from a natural gas-fired power plant
B) Generating electricity from a coal-fired power plant
C) Generating electricity from a nuclear power plant
D) Generating electricity from a solar panel system
Hello!
The answer to this question is: D) Generating electricity from a solar panel system.Thank you for asking this question!
It would be greatly appreciated if you thanked me and marked me as the brainliest!
Have an amazing day.
The energy transformation which produces electricity and is least likely to
negatively impact the environment is generating electricity from a solar
panel system.
Generating electricity from solar panel involves the use of solar energy from
the sun to generate electricity . This type of energy doesn't emit any type of
harmful radiation or release toxic compounds into the atmosphere which
makes it the least likely to negatively impact the environment.
Other options emit any type of harmful radiation or release toxic compounds
into the atmosphere which makes option D the most appropriate.

Which metal pan should the chef choose because it undergoes the largest temperature change for a given input of energy?
The chef should choose the copper pan.
The chef should choose the iron pan.
The chef should choose the aluminum pan.
The chef can choose any of the three pans, because all three pans will undergo the same amount of temperature change.
Answer:
If the chef is in a hurry we would assume he would want the pan to heat up so copper
Explanation:
Answer:
A. The chef should choose the copper pan.
Explanation:
Copper conducts heat well because its atoms contain only one free valence electrons in the outer shell. Elements with a low number of valence electrons transfer heat the best, and copper has only one. Valence electrons move about freely.

What do you think causes a lunar eclipse? (Use your knowledge of solar eclipses and feel free to run the Gizmo to help you.)
Moon reflects the light frim the sun, thats why we are able to see it and it shines in the night. But, we know that Earth revolves around Sun and Moon revolves around Earth. During this revolution, Earth and Moon comes in a position when Earth is in the middle of the Moon and Sun. So, it blocks the light of Sun frim reaching Moon. Hence, we see no reflection and it causes Lunar eclipse.
Answer:
A total lunar eclipse occurs when the moon and the sun are on exact opposite sides of Earth. Although the moon is in Earth's shadow, some sunlight reaches the moon. The sunlight passes through Earth's atmosphere, which causes Earth's atmosphere to filter out most of the blue light.

The elements mercury and bromine are both liquids at room temperature, but mercury is considered a metal, and bromine is considered a non-metal. How can that be? Explain using properties you know of.
Answer:
At room temperature, mercury and bromine are of fluid consistency, it is because their melting or melting temperature is very low, so low that it reaches room temperature.
Compared to mercury and other metals, the more traditional metals have much higher melting temperatures.
On the other hand, bromine is not a metal, since it does not have the ability to oxidize with the presence of oxygen and also does not give up electrons.
Explanation:
Mercury in the periodic table is Hg, and bromine is Br
