Explain why a balloon in hot water expands but balloon in ice water shrinks be sure to include information regarding the (1) number of molecules (2) the temperture (3) the amount of energy 4 the pressure and (5) the volume

I think that the correct answer would be 2.

The molecules in the air are always creating pressure. Countless molecules collide into everything every second, creating a constant force. Before the air in the balloon is heated, the molecules inside are creating as much pressure as the molecules outside, meaning that the balloon stays at equilibrium and neither expands nor contracts. When they get heated, however, the inside molecules start moving with more force. They create more pressure, causing the balloon to expand outward until the pressure equalizes.

dang that balls went far
