Air inside the bottle expands when the bottle is heated. Some of it leaves the bottle until the pressure of the heated air remaining in the bottle equals the pressure of the air in the room. The balloon is then placed over the neck of the bottle and prevents any more air from entering or leaving the bottle. The air inside the bottle cools to the temperature of the ice water. The cooler air inside the bottle takes less space (volume) than it did when hot, so it sucks the balloon inside the neck of the bottle. Air pressure inside the bottle causes the balloon to stretch and enlarge until the air pressure inside the bottle, including the air in the balloon, has the same pressure as the air in the room.
The balloon will inflate.
The hot water heats the air in the system, causing it to expand.
Plastic water bottles can melt when hot water is placed in them due to the low melting point of the plastic material used to make the bottles, such as polyethylene terephthalate (PET). When the hot water comes into contact with the plastic, it can cause the polymer chains in the plastic to break, leading to melting or deformation of the bottle. It is important to use bottles specifically designed to withstand hot liquids to avoid this issue.

they slow down
Plastic bottles are 'blow molded'. Basically air is forced inside a small piece of hot plastic and it expands like a balloon, except that this 'balloon' is inside a form or mold in the shape of the bottle. It is cooled and the bottle shape stays. If the softening point of the bottle is lower than the hot liquid poured in, then the plastic 'balloon' wants to shrink again.
when you but the bottle in hot water the balloon particles push apart and cause expansion
The hot water heats the air in the system, causing it to expand.
The hot water heats up the air inside the bottle, causing it to expand, forcing some of the air out of the bottle and into the balloon, causing it to inflate. The larger the bottle, the more air that will be pushed into the balloon. The air in the balloon will quickly cool and, since hot air is less dense and therefore rises, the cooler air is forced back into the bottle to be heated up. Eventually the air will be a constant temperature and the balloon will reach the limit of inflation. As the water cools, the air cools and the balloon begins to deflate.

the balloon will start to blow up by the heat
This is described by Boyle's law which states that PV = nRT or in English, the product of pressure and volume is proportional to the temperature. Putting the bottle in hot water expands the gas in the bottle which inflates the balloon.
it sinks
Yes! If you heat a bottle with hot water, the balloon would grow bigger and bigger while if you put it under cold water, you would find out that the balloon became deflated again.
it might melt
There is a difference in the density of the gas on the outside and inside. Helium molecules naturally are spaced further apart than nitrogen and oxygen. (N and O are the main components of air) Being further apart makes them less dense than the air. The denser air fill in the space below the balloon and pushes upward. A simple experiment: Find an empty soda bottle with a lid. Fill a large bowl 3/4 full of water. The water is the "air" in our experiment and the soda bottle is the "balloon". Can you push the soda bottle to the bottom of the bowl? What happens when you let go? Water is more dense than air and the same thing that happens to the soda bottle happens to the helium balloon. A side note: Hot air is less dense than cold air. A hot air balloon uses this same method to float passengers.
