Read the excerpt from a reading passage titled "Matter and Energy: Evaporation and Condensation." Condensation An example of con

densation can be seen when drops of water form on the outside of a glass of ice water. The drops seem to appear from nowhere, but they actually form from water vapor in the air. The dew that forms on grass overnight is another example of condensation. Condensation happens when molecules in a gas cool down. As the molecules lose heat, they lose energy. As a result they slow down. They move closer to other gas molecules. Finally these molecules collect together to form a liquid. (Source: Encyclopaedia Britannica, adapted by Newsela staff, 06/02/2017) Describe the process of how dew forms on a blade of grass.
A. Dew forms on grass as water vapor warms up on blades of grass overnight.
B. Dew forms on grass when water vapor forms when molecules cool and separate.
C. Dew forms on grass when water vapor forms when molecules cool and join together.
D. Dew forms on grass when water vapor forms when liquid cools and becomes a gas.

Answer : The correct option is (C) : Dew forms on grass when water vapor forms when molecules cool and join together.

Explanation :

Air contains a small amount of water vapors. When the temperature of an object is lowered than the ambient temperature, the vapors get condensed and small water droplets are formed on the object.

During night time, when the temperature is lowered, the blades of grass become cool. As a result, the vapor molecules slow down and eventually come close to each other. They join together to form liquid water which gets deposited on the blades in the form of dew drops.

The only option that explains this process is option C.

Why fluorine is more electronegative than both oxygen and chlorine.
ziro4ka [17]
Why chlorine has highest electron affinity than fluorine?

This is because the atomic radius increases down a group. The electron gained ends up in the outermost shell. ... Fluorine, which is higher up the group then chlorine, has a lower electron affinity. This is because the electrons in the outermost shell of a fluorine atom are closer together.

The proximate reason for the uptake by plants of nutrients like ammonium nitrate is?
Blizzard [7]

The proximate reason for the uptake by plants of nutrients like ammonium nitrate is homeostatis

<h3>What is homeostasis?</h3>

Homeostasis refers to an organism's ability to regulate various physiological processes to keep internal states steady and balanced.

<h3>How does plant perform homeostatis?</h3>

As water leaves the plant tissues into the atmosphere, it takes energy with it in the form of heat.

Much like when we sweat, this allows the plant to cool and maintain homeostasis.

Similarly, the same process allows plants to  absorb nutrient like ammonium nitrate.

Thus, the proximate reason for the uptake by plants of nutrients like ammonium nitrate is homeostatis.

At a pressure of 782.3 mm Hg and 34.4 °C, a certain gas has a volume of 362.4 mL. What will
german

Answer: v2=331.289mL

Explanation:

Formula for ideal gas law is p1v1/T1=p2v2/T2

P1=782.3mmHg

P2=769mmHg at STP

V1=362.4mL

V2=?

T1=273+34.4=307.4k

T2=273k at STP

Then apply the formula and make v2 the subject of formula

V2= 782.3×362.4×273/760×307.4

V2=77397006.96/233624

V2=331.289mL
