Metals haven't molecules.
When water is heated, its molecules gain energy and move faster, causing them to spread out and take up more space. This increase in movement creates more space between the molecules, leading to an expansion in volume. This is known as thermal expansion and is a common property of liquids and gases when heated.
As the air inside a hot air balloon is heated, its density decreases because the air molecules expand and spread out, becoming less concentrated. This decrease in density causes the balloon to become less dense than the surrounding air, allowing it to rise.
the heat makes the molecules inside the balloon travel faster, pushing outward on the balloon. This, the balloon expands when heated
If the air inside a balloon is heated, the volume will increase because the molecules move faster and spread out, causing the air to expand. Conversely, if the air inside a balloon is cooled, the volume will decrease as the molecules slow down and come closer together.
When you heated the can, the air inside expanded and its temperature increased. As a result, the pressure inside the can also increased since the gas particles moved faster and collided with the walls more frequently.
The molecules move faster
As the iron is heated, the kinetic energy of the molecules increases, causing them to vibrate more rapidly and over larger distances. This increased motion disrupts the ordered arrangement of the molecules, leading to expansion of the solid structure as the molecules move further apart.
They don't necessarily move to another place. However, the movement of the molecules INSIDE the object speeds up. (:
When a balloon is heated, the molecules inside gain kinetic energy and move faster. This causes the molecules to push against the walls of the balloon more vigorously, increasing the pressure inside the balloon. If the balloon is heated too much, it can expand or even burst due to the increased pressure.

When a closed can is heated, the molecules inside the can gain energy and move faster, leading to an increase in pressure. This happens because the increase in temperature causes the molecules to collide more frequently with the walls of the can, exerting more force and increasing the pressure inside.

Depends on the container of the "air particles" and what you mean by "what happens." If it is inside a container that can not expand, then the pressure increases. If it is inside a container that can expand (or is just atmospheric air) then the volume increases. (Pressure * Volume = n * R * change in temperature) On the atomic level, the atoms or molecules (depending on the gas) begin to move more quickly as their kinetic energy increases.
