Which of the following correctly identifies a method of heat transfer that will happen in this situation?
Heat will be transferred from the hot plate to the thermometer through radiation.
Heat will be transferred from the beaker to the thermometer through convection.
Heat will be transferred from the hot plate to the beaker through convection.

Radiation is a method of thermal energy transfer. It refers to the transfer of heat energy that moves–
through empty space.
when objects touch.
only through solids.
in the motion of fluids.
Conduction can only occur between two objects when–
one object is less dense than the other.
both objects are in physical contact with each other.
one of the objects is made of a metal.
both objects are exactly the same temperature.
