How can heat be transferred through matter by the collisions of atoms or through space?
The transfer by collisions of atoms is called conduction. Transfer directly through space is radiationl
What are 3 ways heat is produced?
Conduction, convection and radiation TRANSFER heat; you can't create heat; the law of conservation of energy states that energy cannot be created or destroyed. Therefore, you can't create heat.
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.
What would be the effect of a change in temperature on the resistivity?
A change in temperature generally increases the resistivity of most materials. This is because as temperature rises, the atoms in the material start to vibrate more vigorously, causing more collisions between electrons and atoms. These collisions impede the flow of electrons, resulting in an increase in resistivity. Conversely, at lower temperatures, resistivity tends to decrease due to reduced atomic vibrations and fewer collisions.
Why is vacuum the best insulator?
In order for heat to be conducted, there have to be collisions between atoms or molecules, in which energy is transferred from a faster moving particle to a slower moving particle. In a vacuum there are no particles, hence, no particle collisions and no heat conduction.

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.
The transfer of energy that occurs when molecules collide?
Conduction:The transfer of energy by collusions between the atoms and molecules in a material. So conduction But others think its heat because heats deffinition is Heat: A transfer of energy from an object to another due to a difference in temperature.
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.

Why is trapped air a good insulator?
Because air is a very low density material, there are not a lot of atoms per unit volume to engage in heat transfer type collisions, and if the air is trapped and therefore motionless, it does not carry heat away with it by moving to another location.
