Many instruments and volumetric glassware are calibrated at 20 oC.
It isn't clear what experiment you are talking about, but pressumably the idea was to detect whether the temperature changed.
hot oil.
No- hydrogen is a gas at room temperature.
No, it is a highly viscous liquid, do a search on the Pitch Drop Experiment.
This is an experiment. it will change from liquid to solid.
You need to specify what type of experiment you are asking about.

it depends on where you put it and of the room temperature i hope you good luck
This is to record the temperature change which is part of your data. This allows you to draw conclusions for the experiment.
I would store coke in a cold place if I were to do that experiment xD

LiCl
Technetium is a solid at room temperature.
CaCO3 is solid at room temperature
If it is a gas, then it is most likely chlorine.
