Answer:
C: increases
Explanation:
Temperature is directly proportional to volume. If the temperature of a substance increases, the volume also increases. If the temperature decreases the volume also decreases.
According to Charles's law "the volume of fixed mass of gas varies directly as its absolute temperature if the pressure remains constant". Although this is an ideal gas law, it is also applicable to most substances.
As the temperature is raised, the volume also behaves proportionally that way.
Nitrogen and oxygen are the most prevalent in the atmosphere.
<span>This is the process of radioactive dating. Carbon is used because it is an essential part of all living organisms and has a radioisotope that decays with a half-life of 5000 years. This ratio makes it easy to date an object using Carbon-14. Uranium is used for objects that have a much longer half-life, outside the bounds of carbon's abilities.</span>
Answer:
The elements with completely filled shells are classified as noble gases
That is why we only see noble gases on the rightmost corner of the periodic table, it is because they have the maximum number of electrons in a shell
<u>Examples of noble gases</u>
Helium , Neon , Argon and Krypton are some examples of noble gases
The answer is : 17.5 liters drained and replaced by 17.5 liters of 100% solution.
x = amount drained and replaced
(70-x) = remaining amount of 20% solution
<span>.20(70-x) + 1.00(x) = .40(70)
14 - .2x + 1x = 28
1x - .2x = 28 - 14
</span><span>.8x = 14
</span><span>x = 14/.8
x= 17,5 ( 17.5 liters drained and replaced by 17.5 liters of 100% solution)
</span>
