The correct answer is: As the kinetic energy in a substance's atoms increases, its thermal energy increases, and vice versa.
To understand the relationship between kinetic energy and thermal energy, it is important to have a basic understanding of these concepts.
Kinetic energy refers to the energy possessed by an object due to its motion. It is dependent on the mass and velocity of the object and can be calculated using the formula KE = 1/2 mv^2, where KE is the kinetic energy, m is the mass, and v is the velocity.
Thermal energy, on the other hand, refers to the total energy possessed by the atoms and molecules within a substance. It represents the sum of the kinetic and potential energies of these particles. In other words, thermal energy is the energy associated with the random motion of particles within a substance.
Now, the relationship between kinetic energy and thermal energy is that an increase in kinetic energy of the particles within a substance leads to an increase in its thermal energy, and vice versa. This is because the higher the kinetic energy of the particles, the greater their random movement, which results in more collisions and interactions between particles. These collisions and interactions transfer energy among the particles, leading to an increase in the overall thermal energy of the substance.
Similarly, if the kinetic energy of the particles decreases, their movement becomes slower, resulting in fewer collisions and interactions. Therefore, the overall thermal energy of the substance decreases.
It is important to note that thermal energy represents the average kinetic energy of the particles within a substance, while kinetic energy refers to the energy possessed by individual particles. Therefore, a change in the average kinetic energy of the particles will result in a corresponding change in the thermal energy of the substance.
The correct response is:
As the kinetic energy in a substance's atoms increases, its thermal energy increases, and vice versa.
