<u>Answer:</u>
211.9 J
<u>Explanation:</u>
The molecules of water release heat during the transition of water vapor to liquid water, but the temperature of the water does not change with it.
The amount of heat released can be represented by the formula:

where
= heat energy,
= mass of water and
= latent heat of evaporation.
The latent heat of evaporation for water is
and the mass of the water is
.
The amount of heat released in this process is:
211.9 J
Answer:
0.125 mg
Explanation:
<em>The correct answer would be 0.125 mg</em>
<u>According to the conversion factor, one milligram of a sample is equivalent to one thousand micrograms of the same sample.</u>
milligram = 
microgram = 
Hence,
1 milligram = 1000 micrograms or 1 microgram =
milligram
Therefore, 125 micrograms will be:
125/1000 = 0.125 milligram
Answer:
571.81 mL
Explanation:
Assuming constant pressure, we can solve this problem by using <em>Charles' law</em>, which states that at constant pressure:
Where in this case:
We <u>input the data</u>:
- 852 mL * 200 K = V₂ * 298 K
And <u>solve for V₂</u>:
The new volume would be 571.81 mL.
