Unit 8 Vocabulary
The transfer of heat that occurs
when two objects of different
temperatures touch; matter
must be in direct contact
The transfer of heat from one
place to another, when matter is
in direct contact and is in motion
due to density changes in liquid
or gas
A form of energy emitted and
absorbed by charged particles
The transfer of heat that occurs
through empty space, matter
need not be in direct contact or
be present
The energy of heat, which
transfers from hotter objects to
colder objects
