When we place a water bottle with cold water on top of a water bottle with hot water the particles in the hot water bottle rise, pushing the cool particles to the bottom. This is a type of heat transfer called convection. Basically, the hot particles in the hot water bottle rise to the cold water bottle at the top and the cool particles in the cold water bottle at the top sink to the hot water bottle at the bottom. This is one of the three heat transfers. Convection occurs in gases and liquid.
Lots of things affect this. Also the original temperature of the water, the temperature outside and where the bottle is left.
it might melt
It will implode if it is thin and you put a lot of pressure on it. You wouldn't be able to do it with your mouth if that's what you are asking.
It does melt. If your honey crystalizes in the bottle, you can turn it back to liquid by putting the bottle in hot water.
Hot water pipe rust first as compared to the cold water pipe for the same chemical composition of the water.
Cold water pipe.
This is a sign of residue in the hot water pipes. i guess at your part of the world, you must be using corrosive type of water pipes. The heat in the water helps oxidization of the inside of pipe and when the same pipe is not used to transfer of water in the pipe, existing water in the pipe caused corrosion so when the tap is opened after a while, the water that comes out is brown. To avoid this, you need to use the tap more often to stop the brown build up inside the pipe.
The best way to safely microwave a hot water bottle is to heat the water in a separate microwave safe container in the microwave and then put the microwaved, hot water into the water bottle.

You can use a hot water bottle. Put the hot water bottle on the pain and it should sooth it
That's just how long it takes to get the water that is sitting in the pipe out. Unless you have a circulating pump on the line so that there is always hot water at the faucet, it always takes a bit of time for the water to get hot. The hot water is in the tank, not the pipe connecting it to the faucet. There is nothing in the pipe to keep the water hot.
hot
The hot water heats the air in the system, causing it to expand.
air lock in hot water pipe
when you but the bottle in hot water the balloon particles push apart and cause expansion
The air in water bottle expands
