She activates it and tucks it into the glove she is wearing. She holds her hands together, and before long, her hands are warm. Which best describes how her hands were warmed? A. Heat was transferred by conduction, resulting in an increase in kinetic energy.
B. Heat was transformed by convection, resulting in the conservation of energy.
C. Thermal energy was transferred by currents, resulting in an increase in kinetic energy.
D. Heat was transformed by radiation, resulting in an increase in kinetic energy.
