In a solid state, molecules are packed closely together but they do not touch each other in the traditional sense. There is a small distance between molecules due to the forces of attraction and repulsion between them.
Gas particles do not touch each other in the way that solid particles do. The particles in a gas are in constant motion and are separated by large distances relative to their size. However, they can collide with each other and with the walls of their container.
An object is solid if it has a definite shape and volume, maintains its shape under normal conditions, and does not flow like a liquid. Solids also have strong intermolecular forces that hold their particles together.
An example of conduction is when a metal spoon placed into a hot cup of coffee becomes warm to the touch. This is because the heat from the coffee is transferred to the spoon through direct contact, causing the molecules in the spoon to vibrate and generate heat.
The transfer of energy through touch involves the interaction of molecules at the surface of two objects. When one object with higher kinetic energy comes into contact with another object with lower kinetic energy, energy is transferred from the higher-energy object to the lower-energy object through the vibrations of molecules at their interface. This results in a change in temperature or other physical effects.
When you touch a hot pan, the heat is transferred from the pan to your hand by a process called conduction. The molecules in the pan vibrate faster due to the heat, passing the energy to the molecules in your hand, which causes them to vibrate faster as well. This increase in vibration is perceived by your nerves as heat.
When fast moving molecules touch other molecules, it is called a collision. These collisions can lead to the transfer of energy and changes in the motion or state of the molecules involved.
gas is a state of matter that can be squashed.
Heat transfer
When fast-moving molecules touch, they undergo collisions that result in energy transfer. This transfer of energy can lead to an increase in temperature if the molecules are in contact with each other for long enough. If the collisions are frequent and energetic, it can lead to a change in state, such as from a solid to a liquid or a liquid to a gas.

48 states touch at least one other state. Some states of the 48 touch at least 3 other states. Only Alaska and Hawaii don't touch another state.
Alaska and Hawaii
Alaska is not an island. It does not touch any other state.
Liquid.
Hawaii.
Solid: Molecules are tightly packed together into a fixed shape, so the molecules only have room to vibrate in place. ex: a classroom Liquid: Molecules have room to spread out and can slide past each other and takes the shape of the container it's in. ex: a hallway Gas: Molecules have room to go wherever and don't touch each other but still takes form of it's container. ex: outside; parking lot
48 states touch at least one other state; all but Alaska and Hawaii.
