Is this true when you touch a hot plate, the transfer of heat from the plate to your hand is called

Conduction

Explanation:

As the heat energy is carried out in the form of movement of particles of matter and is transferred by there vibration around the other objects and these when in contact with a foreign body, while the radiation is the upward and downward heat transfer in space and takes place through an electromagnetic waveform  As expressed by the laws of thermodynamics in the process of transfer and spread of heat from place to another in the surroundings.

Unique question.well, using science, you cannot create or destroy even if you do eat yourself so you would not grow twice as big, nor would you disappear. you would stay the same but change states potentially, or at least change your appearance (obviously).hope this . keep up these unique questions.
