Answer:
a. molecular interactions.
Explanation:
Conduction is thermal energy transfer by molecular interactions. Therefore, conduction involves the transfer of electric charge or thermal energy due to the movement of particles. When the conduction relates to electric charge, it is known as electrical conduction while when it relates to thermal energy, it is known as heat conduction.
In the process of heat conduction, thermal energy is usually transferred from fast moving particles to slow moving particles during the collision of these particles. Also, thermal energy is typically transferred between objects that has different degrees of temperature and materials (particles) that are directly in contact with each other but differ in their ability to accept or give up electrons.
Some examples of conductors include metal, steel, aluminum, copper, graphite, etc.
Hence, conduction is thermal energy transfer as a result of the movement of electrons and collision between the molecules of an object.

Answer:
Explanation:
outside air must be mixed with return air at some point in time because here is an example a warm current of air comes in contact with a cold current of air the warm current has to cool down so it could mix with the cold current or if they don´t mix they would continue to bump into each other and probably cause a tornado. probably.
Answer:
D=1.0x10^-5 m^2/s
Explanation:
the data given by the exercise are as follows:
T=308 K
d=1 cm
PA=0.195 atm
pL=0.85 g/cm^3
The expression for binary gas-phase diffusion coefficient is equal to:
substituting the values in the diffusion equation:
from Appendix J-1 from Welty:
298 K, D=9.62x10^-5 m^2/s
At 308 K, we have the following:
