kinetic energy that occurs within a molecule when the bonds are
stretched or bent? Name the form of kinetic energy that occurs
within a molecule when the bonds are stretched or bent? vibrational
vibrational
Slide 5
Describe the relationship between two systems in thermal
equilibrium? No energy exchange.
Slide 6
As the temperature of a substance increases, its volume tends
to increase due to thermal expansion.
Slide 7
