As long as the fuel system is in good working order, meaning that it is sealed and the gas cap closes and seals, no. And no.
Fuel systems are made to prevent the vapors from going anywhere but into the engine.
The worst that could happen would be:
1. the gas will go stale meaning the octane will go lower
2. if the tank is left at half or lower on a regular basis, condensation will form in the tank. These water drops can cause rough running, rust and freeze in the winter preventing the car from starting.

If you leave the gas cap on and have no leaks, you will lose hardly any. Gasoline has a shelf life of approximately 6 months before it starts to form varnish. This is not good for anything. You could try using gas stabilizer if you are going to park for an extended amount of time (found at any parts store). As for moisture condensation, how did the moisture get in your tank? Did you fill it with a garden hose? This type of thinking is older than dirt. Don't worry about it. Never in 30 years have I seen water in fuel from condensation.

fairly, even if the tank is sealed. The evaporated vapor remains in the tank, and will strengthen the most concentration of the gasoline vapor in the air in the tank. formerly lengthy it reaches the saturation aspect and under no circumstances more advantageous evaporates. If the temperature cools down again, some will condense again into liquid.

Unless the car is parked for a very, very long period of time, no it won't evaporate. At least not enough to notice, but the fuel will go bad in just one season. If the car is going to sit for 4 or more months without putting fresh fuel in it, you need to go to the parts store and buy some gas stablizer and put it in the fuel to keep it from going bad. This is why they recomend dumping the fuel out of lawn mowers and weed eaters every years.

Yes it happens. but very slowly. If u park your car in a very hot place it could happen a bit faster. That's not a fault of cars. Petrol, Octane, Diesel always evaporate from every place automatically.

You will always have a very small amount of evap...and I mean very small, but if gas sits in any type of engine for to long it turns to a lacquer type substance which will ruin your engine. If you do use your car even if it is only every once in a while you have nothing to worry about. If it sat for a few years I would drain the tank and put clean gas in it and make sure you prime it with clean gas.

if it is a pollution controlled car , no , an older one with a vented gas cap may over time loose some fuel to evaporation , the concern is moisture condensation .

Yes it will and it starts from the moment you fill up your tank. It evaporates faster in heat.

yes thats why there is a vent in the cap, and don't block it if you do it will blow up the tank in time, it must vent
