Two iron blocks are the same size. one block has a higher temperature than the other. which describes the thermal energy of these blocks?
a. lower temperature means greater potential energy, which means the colder block has greater thermal energy.
b. lower temperature means greater kinetic energy, which means the colder block has greater thermal energy.
c. higher temperature means greater potential energy, which means the warmer block has greater thermal energy.
d. higher temperature means greater kinetic energy, which means the warmer block has greater thermal energy.
