Cold air are more denser than the warm air.
<span>
It is because the molecules of cold air are closer together and the bonds are absorbing less energy and therefore do not move as much.</span>
 
Hope this helps!

How does this sentence violate the principles of objectivity in writing a summary?
Mnenie [13.5K]
You didn't provide the sentence that is relevant in this case, however, generally if you would like to be objective in a sentence, you shouldn't include possible issues such as subjective thoughts, judgments, and similar things which have a negative impact on objectivity (and in reality destroy any remaining objectivity in a sentence).

In which section of the nephron does the filtrate have a higher osmolarity than the blood when it enters and lower osmolarity th
Liula [17]
I believe it is the ascending loop of henle. In the ascending portion, the loop becomes impermeable to water and instead the cells of the loop, actively reabsorb the solute; thus water is not reabsorbed but ions are readily reabsorbed. As the ions are reabsorbed the concentration becomes more and more hypotonic until it reaches 100-150 mOsm/L. Therefore, the ascending loop is called the diluting segment of the nephron due to its ability to dilute the fluid in the loop from 1200 to 100 mOsm/L.

A gas has an initial volume of 2.4L at a pressure of 1.5 atm and a temperature 273K. The Pressure of the gas increases to 4.5 at
likoan [24]

Answer:

The answer to your question is  V2 = 0.92 l

Explanation:

Data

Volume 1 = V1 = 2.4 l

Pressure 1 = P1 = 1.5 atm

Temperature 1 = T1 = 273 °C

Volume 2 = V2 = ?

Pressure 2 = 4.5 atm

Temperature 2 = 313 °K

Process

To solve this problem use the Combined gas law

                     P1V1/T1 = P2V2/T2

-Solve for V2

                     V2 = P1V1T2 / T1P2

-Substitution

                     V2 = (1.5 x 2.4 x 313) / (273 x 4.5)

-Simplification

                     V2 = 1126.8 / 1228.5

-Result

                     V2 = 0.92 l

Describe the procedure of water reaching the leaves from the roots of a plant
Lisa [10]
The water enters the xylem first by osmosis. Water moves from the soil to the root hair cell down a water potential gradient, and to the root cortex cell from a higher water potential to a lower water potential, this process will be repeated until water enters xylem. Because transpiration is occurring in the leaf, water is lost so there is a lower water potential inside the leaf. Osmosis moves water from the xylem to the leaf because the xylem has a higher water potential. Water moves from the xylem to the cells of the leaf. This pulls water up the xylem via cohesion which is the process of water molecules attracting each other and sticking together. Water does not fall down the xylem as here is adhesion which is the process of water molecules sticking to the inside of the xylem.
