False because that’s not it’s function
Because the air right above your hot pan of water is so warm, the water vapor can be quickly absorbed there. When the heat is removed, the hot convective up current from the pan vanishes and is replaced with cooler air that can no longer contain as much moisture, which makes the condensing water vapour visible.
First, it's important to discuss the "steam" that is produced by the hot water. While we refer to it as steam, it is not. Water that is heated above 100 degrees Celsius produces steam. The only area in the kitchen where you can see it clearly is if you look very closely at the spout of a boiling kettle. The first 5mm (1/4") of the liquid will be clear when it is boiling very near to the spout.

Answer:
Explanation:
Half life of Nobelium-253 is 97 seconds . That means after every 97 seconds half of the Nobelium amount will be disintegrated .
Time taken in bringing the sample to laboratory = 291 seconds
291 second = 291 / 97 half life
n = 3
N = 
N₀ is original mass , N is mass after n number of half life.
N = 5 mg x 
= .625 mg
Only 0.625 mg of Nobelium-253 will be left .
The compound is CH₃CH₂CH₂NH₂
when naming the compound the C chain has 3 C atoms and they all are in a single chain therefore alkane chain is propane.
It has a -NH₂ group attached to the C therefore functional group is 'amine'
-NH₂ is attached to a terminal C atom therefore when numbering the C atoms the C attached to the substituent should have the lowest number therefore C atom with NH₂ is carbon atom 1
therefore name of the compound is 1-propanamine
1 mole --------- 22.4 ( at STP )
2.66 moles ---- ?
V = 2. 66 * 22.4 / 1
V = 59.584 / 1
V = 59.584 L
hope this helps!
