How does a wire create resistance?
A wire creates resistance due to collisions between electrons and atoms in the wire's material. These collisions impede the flow of electrons, causing resistance to the current passing through the wire.
Explain the energy transfer on the atomic level?
Energy transfer on the atomic level occurs through interactions such as collisions between atoms or through electromagnetic forces like radiation. When atoms collide, kinetic energy is transferred from one atom to another. Electromagnetic forces can transfer energy through the emission or absorption of photons by atoms.
What is the transfer of thermal energy by the collisions between particles of matter?
In loose terms, increased energy associated with increased temperature is heat, or thermal, energy. We say heat flow from hot to cold and that is true. The simple and common mechanism for this heat to move is through the collisions between the more energetic atoms and molecules on one region with the less energetic atoms and molecules in a neighboring region. That is a simple explanation appropriate to simple materials in simple situations. The thermal conductivity of a material is a quantitative measure of how much heat will flow through a material per unit time for a given temperature gradient. In the simplest materials the mechanism of heat transfer may be described at the microscopic level as transfer of energy through collisions between atoms and molecules. In a higher temperature region region the atoms and molecules have more kinetic energy than in a low temperature region. In general, when two objects collide, the higher kinetic energy object transfers energy to the lower kinetic energy object. (This is more complicated than it sounds.) Thus, as particles collide with neighboring particles and the process is repeated billions of times with billions of particles, they tend towards an average kinetic energy. For two adjacent regions, one hot and one cold, the kinetic energy moves from the hot to the cold in an average sense. This is called thermalization or thermal equilibration. Heat energy, or thermal energy, has moved from the hot region to the cold region. Thermal energy is more than kinetic energy and also includes potential energy between atoms and molecules and may also include chemical and electronic energies. Nonetheless, it is a fundamental law of thermodynamics that two objects left in thermal contact will eventually arrive at the same temperature and that temperature will be somewhere between the initial two temperatures. In simple materials, it is the collisions between atoms that serves to transfer the kinetic energy (some of which may become potential or another form of energy) so that the temperature of a material moves toward a uniform temperature. The basic answer to the question is that collisions between particles allow the transfer of energy in matter. There is a caveat. When the matter is not simple, such as in a conducting metal material, there is a strong interaction between the electronic structure and the movement of the constituent atoms. The idea of "collisions" is inadequate since there is not one atom interacting with one other atom but the motion of all atoms are interconnected through the electronic structure. Indeed, the concept of collisions at the atomic level must be employed with care since it is a concept derived from or macroscopic experience with macroscopic objects.
Why do certain materials have electric resistance?
Certain materials have electric resistance due to the collisions between the electrons and atoms within the material, which hinders the flow of electric current. The resistance is caused by factors such as the type of material, temperature, and impurities present in the material.

Why thermal conductivity increases with increase in pressure?
Increasing pressure leads to closer packing of atoms or molecules in a material, which enhances the transfer of thermal energy through collisions between particles. This results in a higher thermal conductivity as more collisions occur, allowing heat to move more efficiently through the material.
Why solids pick up heat fast as compared to air?
Heat transfer takes place due to collision in atoms (of which everything around us is mad). In solids these atoms are near to each other but in gas atoms are very very far from each other. So in case of solids, it is easier to transfer the heat in form of collisions but in air it is difficult to transfer these collisions. Note: Heat is transferred in form of collisions because heat increases speed of atoms. This speed when transferred to adjacent atoms by collisions, transfers the heat.

What is it called when free electrons in metals transferring energy by colliding with other atoms or electrons?
It is called thermal conduction, where free electrons in metals transfer energy through collisions with other atoms or electrons, facilitating the flow of heat throughout the material. This process is a key mechanism for heat transfer in metals.
Collisions of helium atoms with the walls of a closed container cause what?
Gas Pressure
Do atoms move between your bodies and other objects?
No, atoms typically remain within the bounds of objects. While some atoms can transfer between bodies through processes like breathing or consuming food, they do not freely move between objects without a specific mechanism for transfer.
How can heat be transferred through matter by the collision of atoms?
Since that's what heat is (the motion of atoms), how better to transfer than by random collisions? yes.
When hotter atoms c they transfer their energy to colder atoms?
When hotter atoms come into contact with colder atoms, energy is transferred from the hotter atoms to the colder ones through collisions between the particles. This transfer of energy causes the colder atoms to gain kinetic energy and increase their temperature. Heat flows from hot to cold until thermal equilibrium is reached.
