Molecules in the gas state are strongly attracted to each other but change positions?

Does decomposition have chemical reactions with different molecules trade position?
A decomposition reaction does not involve molecules trading positions. When two different molecules or pairs of molecules change position with one another, the chemical reaction is known as an exchange reaction.
What process causes water to change color from food coloring?
This is the diffusion of the coloring agent molecules in water.
Why isn't dissolving sugar a chemical change?
Because the sugar stays sugar and the molecules themselves are unchanged, it does not change into another substance. Also, the process can easily be reversed by the physical process of evaporating the water.
When ice starts to melt what happens to the temperature until it completely changes to all water?
During a change of state (phase) there is only a change in the potential energy of the molecules, not the kinetic energy. The energy is used by the molecules to rearrange themselves into positions they have in the liquid state.

Molecules in what state are strongly attracted to each other but can change positions?
I think it is water molecules
What is the process by which molecules at the surface of a liquid absorb enough energy to change to a gaseous state?
Evaporation is the process by which molecules at the surface of a liquid absorb enough energy to change to the gaseous state.
Does decomposition have chemical reactions with different molecules trade position?
A decomposition reaction does not involve molecules trading positions. When two different molecules or pairs of molecules change position with one another, the chemical reaction is known as an exchange reaction.
What process could cause a material to change its state from gas to liquid?
removing energy from the molecules
Is it a chemical reaction when a substance changes its form?
The change of form in not a chemical process; it is only a physical change, the molecules remain unchanged.
What process causes water to change color from food coloring?
This is the diffusion of the coloring agent molecules in water.
Which statement best explains the observed change in size of the potato cubes?
water left the cube by the process of osmosis

What is the process called when water leaves ponds into the atmosphere and back to the ponds?
Vaporization (aka. evaporation) is the process in which the molecules in liquid water break their intermolecular forces of attraction and become gas molecules. These H2O gas molecules have no where to go, except into the atmosphere. So the process for when these gas molecules change back into liquid molecules and leave the atmosphere, (or when it rains) is called condensation. This water of course goes back into different water sources such as ponds, lakes, and oceans.
Is formation of a gas is a chemical change?
The formation of gas is:- a chemical process if the gas is the product of a chemical reaction- a physical process if the gas is the product of a change of phase as sublimation and vaporization
When ice starts to melt what happens to the temperature until it completely changes to all water?
During a change of state (phase) there is only a change in the potential energy of the molecules, not the kinetic energy. The energy is used by the molecules to rearrange themselves into positions they have in the liquid state.
