a: Thermal energy ~
b: sound of popcorn in a glass bottle
What:
Thermal energy, perceived as warmth to human touch, is caused by the vibration of molecules of an object. You can't directly feel the molecules vibrating;you feel the effect. Now think about a glass bottle of un-popped popcorn. If you shake it and the popcorn hits the inside of the bottle, it makes noise. This is somewhat like the molecules vibrating and creating perceptible thermal energy.
