QUESTION 1
What is the relationship between the kinetic energy of molecules in an object and the object's temperature?
The total kinetic energy of the molecules is not affected by a change in temperature.
The kinetic energy always increases whether the temperature increases or decreases.
As the temperature increases, the kinetic energy of the molecules increases.
As the kinetic energy of the molecules decreases, the temperature increases.
