Molecules of air are mainly nitrogen and oxygen, N2 and O2. The '2' subscript means each molecule contains two atoms. The molecules themselves do not change with changes in energy, pressure, temperature etc.
I'm not sure what you mean by potential energy turning into kinetic energy. I can visualise one route, where you have air pressurised in a container, then you release the pressure and the air rushes out, gaining kinetic energy. In this case the molecules of air will soon collide with the air that they are going into and be slowed down until mixed and at the same pressure and temperature. The density of the air will be lower than it was in the pressurised container. This means not so many molecules in a unit volume, so their mean distance apart will be greater. If that is what you mean by 'expand' then I agree, but the molecules themselves are not altered.
What else can I help you with?
Is holding a spring so tight that it doesn't expand in your hand Kinetic or potential energy?
potential
Is the energy stored in a compressed spring called kinetic energy?
No, the energy stored in a compressed spring is called potential energy, specifically elastic potential energy. When the spring is released, this potential energy is converted into kinetic energy as the spring moves and accelerates.
Can air expand?
Air expand on heating as heat in a gas is the random kinetic energy of the molecules. Pressure is the result of kinetic energy in one direction, so an increase in heat leads to an increase in pressure, which leads to expansion against the surroundings.
What energy is compressed springs and stretched rubber bands?
Potential energy. When springs are compressed or rubber bands are stretched, they store potential energy due to their deformed state. This potential energy can be released as kinetic energy when the springs expand or the rubber bands contract.
What form of energy does a compressed spring have?
A compressed spring has potential energy stored in the form of elastic potential energy. This potential energy is ready to be released as kinetic energy when the spring is allowed to expand and return to its natural state.
Does air expand when its warmed?
yes it does.
What type of energy is a balloon expanding?
The energy involved in a balloon expanding is primarily potential energy, which is stored in the elastic material of the balloon as it is stretched. When the balloon is released, this potential energy is converted into kinetic energy, causing the balloon to expand.
Why does the volume of a heated solid decrease?
When a solid is heated, the molecules gain kinetic energy and vibrate more vigorously, leading to an increase in the space between molecules. This increased kinetic energy causes the solid to expand, which can result in a decrease in the overall density and volume of the solid due to the increased space between molecules.
What do you cause when you squeeze the coils of a spring together?
Squeezing the coils of a spring together stores potential energy in the spring. When released, this potential energy is converted into kinetic energy, causing the spring to expand back to its original shape.
What forms of energy are used when you are bouncing on a trampoline?
When bouncing on a trampoline, potential energy is converted to kinetic energy as you jump up, and vice versa as you descend. The springs on the trampoline also store and release elastic potential energy as they compress and expand.-friction and air resistance also play a role in converting kinetic energy into other forms of energy.
What expands when it is heated?
When heated, most substances expand due to the increase in kinetic energy of their atoms or molecules. This leads to an increase in the average distance between the particles, causing the substance to expand.
Why does the volume expand when heat is added to water?
When heat is added to water, the water molecules absorb the energy and move further apart, leading to an increase in kinetic energy. This increase in kinetic energy causes the molecules to move faster and spread out, resulting in the expansion of the water volume.
