That cause is that something metallic [coins, keys, or something similar] in the pocket contacted the battery's two terminals, created a short circuit, and thus a very heavy drain on the battery. That heavy current drain rate caused the battery to heat up.
This is a very dangerous practice, and many times has been documented to have caused extremely severe and painful BURNS to people who have ignorantly carried batteries in their pockets. It it also has been documented that such shorted batteries can and have exploded causing severe and painful injuries.
Do NOT carry batteries in your pocked, BUT... IF you are going to do so, cover both terminals with a plastic terminal cap [like comes with new 9 volt batteries], or securely cover the terminals with electrician's tape.

Can you use a 9.6 volt DC drill battery to extend the life of a standard 9 volt DC electronic item?
no, a 9 volt battery is small (goes in a smoke detector) a 9.6 volt battery is much larger, and it is not a DC battery (direct current) but NiCd (nickel cadmium.) two totally different things.
What happens to the current in a circuit if a 1.5 volt battery is removed and is replaced by a 9 volt battery?
Current will go up by a factor of 6 times in that scenario.
Does a 9 volt battery light a light bulb?
Yes, for about .1 second, then it will blow the lamp. A 9v battery will however light three 3.5v lamps.
Is a 9 volt battery ac or DC?
All Batteries are DC or Direct Current.
Does a 9 volt battery have more energy than a 1.5 volt battery?
A D cell battery has a voltage output of 1.5 volts, while a 9 volt battery produces about 9 volts. This is just the potential energy though. D cells provide far more current for a longer time then a 9 volt battery. In terms of overall power output, a D cell in give you many times more power than a 9 volt battery. Physical size, in this case is a good indicator as the material inside is the same.
What Happens if a 9 volt battery touches another 9 volt battery?
It heats up very hot and may explode.
Can you use a 3 volt charger for a 9 volt battery?
No
Can you use a 6 volt charger for a 9 volt battery?
No, the battery will be overcharged and battery damage will occur if it is done.
Is a lead acid car battery the same as a 9 volt alkaline battery?
No, a lead acid battery is a wet cell battery and a 9 volt alkaline battery is a dry cell battery.
Can you use a 9 volt charger for a 6 volt battery?
This is not advised! The 9-volt charger might have a current limiter so that nothing burns up, but it any case if left on it will destroy the 6 volt battery by overcharging. A 6-volt charger is not expensive.
Can a 9 volt charger be used to charge a 7.2 volt battery?
no
How fat is a 9 volt battery?
1.3cm
Where can you find dcs?
a 9 volt battery
How do you reboot a rechargeable 9 Volt battery?
buy a battery charger
What does a battery clip do?
it operates a battery,mostly a 9 volt battery
What is the difference between a 9 volt battery riding car and a 12 volt battery car?
One is 9 volts and the other is 12 volts. They do not interchange!
Can you use a 9 volt adapter to charge a 19 volt notebook battery?
No.No.
