No, that will have no effect on the battery.
Dirty connection
Overcharging.
A car battery in any car would drain due to a short in the electrical system.

Yes it can. Especially if the battery has a low charge to begin with or it is an old battery.
your car ac will only blow hot air when there coolannt in the car is finished or the car is oveerheated.
Parasitic voltage drain. Are you leaving something like an inverter plugged in? If you installed a new car stereo or amp for example and connected to a power source that is "hot" all the time, whatever is on that line will drain the battery all the time.
Something causes a slow drain on your battery. As it does, your battery slowly discharges. If you know that your car will be not used for several months, you might try disconnecting on of the battery terminals.
Yes. The charging causes a chemical change in the electrolyte of the battery.
To hot wir a car you need jump leads. You need to connect the battery in your car to the battery in another car that is working using the jump leads. Then when you start up car #2 it will give car#1 enough electricity to start itself. From there, it will recharge itself as you drive.
Pouring hot water on a car battery may temporarily help dissolve some of the corrosion, but it is not a recommended method as it can potentially damage the battery. It's best to use a mixture of baking soda and water to clean corrosion from a car battery.
