That depends on how close you are to the equator, in coulombia the temperature barely changes wile in south Canada it changes every season
The pointy things that hang down from the cave's ceiling are stalactites. (A)
The pointy things that grow up from the cave's floor are stalagmites.
(I imagine wearing shorts and hiking through tall grass in the Summer, and I say to myself "When the Mites go up, the Tights have to come down.".)
<span>Answer:
The carbons on the closures are sp² hybridized, with a p-orbital for the 'second' bond in the twofold bond with their neighboring carbons.
They have those sp² orbitals covering with the s from the hydrogen, and they have a p covering in the pi bond with the neighboring carbon. They likewise have a sigma bond with the neighboring carbon I'll get to.
The center carbons each have two pi bonds with their neighbors, leaving sp hybridiaztion for the rest. So they have sp/sp² with the end carbons, and sp/sp with each other. (What's more, they likewise have p/p in the pi bonds).
So the total list is:
s/sp²
p/p
sp/sp²
sp/sp</span>
