liq [111]
<h2>Answer</h2>

The volume will be<u> 50 L</u>

<h2>Explanation</h2>

From Kelvin Law of Temperature, we know that

V_{1} T_{1} =V_{2} T_{2}

We know that

V_{1} = 200 L

T_1 = 100 K

T_2= 400 K

So,

V_{2} = V_{1} T_{1}/T_{2}

V_{2} = 200*100/400

V_{2} = 50 L

The answer of the givern question is 50L

mel-nik [20]

Answer:

Condensation is the process of water vapor condensing into liquid water.

Explanation:

"Water condenses on a can of cold soda. Water vapor in the air reaches its dew point as it cools in the air around the can, forming liquid drops of water. Condensation is the process where water vapor becomes liquid. It is the reverse of evaporation, where liquid water becomes a vapor." -National Geographic"
