In my car the coolant resevoir plastic is very hot after driving (even after relatively short distances - engine at mid temp). Is this normal? It looks like a wet ceiling with beading cooland on the top of the resevoir.

Be careful. It should be hot!
The beading is condensation.
An engine throws a LOT of heat, and anything under the hood will be hot until the engine cools.

yes cars use what it called a recovery system. as the coolant gets hotter the coolant expands and fluid from the radiator will dump into the reservoir and as the engine cools then recover it back. that is why the reservoir will have a hot and cold level marked on it. be sure not to overfill it or it will dump the excess out and make a mess.

It is normal.
The coolant is drawn in and out of the resevoir as needed. This is done when pressure opens the radiator cap, and expansion and contraction forces go to work.

Yes. That is the boiled over water so to speak from the engine block after it gets to running temprature and the fluid expands.
If that didn't get hot, then that would mean your thermostat isn't working and letting the water flow from the radiator to the block.

Yes, the coolant is exchanging heat from your motor. It should always be hot during and immediately after driving.

The water in the overflow will be the same temperature as what is in the radiator.

Yes. And the heating elements should be cool!
