Substance A is initially warmer than Substance B. Conduction takes place between the two substances. Describe the relationship between kinetic energy and temperature by identifying changes to both as conduction took place. Explain why these changes occurred and describe how the objects were affected.(2 points)
As conduction takes place between Substance A and Substance B, the kinetic energy of particles in Substance A decreases while the kinetic energy of particles in Substance B increases. This results in a transfer of thermal energy from Substance A to Substance B.
The decrease in kinetic energy of particles in Substance A occurs because as they come into contact with the particles in Substance B, some of their kinetic energy is transferred to the cooler particles. This transfer of energy causes the particles in Substance A to slow down, resulting in a decrease in their kinetic energy.
On the other hand, the increase in kinetic energy of particles in Substance B occurs because they receive some of the thermal energy transferred from Substance A. These particles gain kinetic energy and start moving faster, increasing their temperature.
Overall, the transfer of thermal energy through conduction causes a decrease in the temperature of Substance A and an increase in the temperature of Substance B. The temperature difference between the two substances gradually decreases as conduction continues, until an equilibrium is reached where their temperatures are equal.
