Which statement best describes the process of heat transfer?
Heat flows from areas of high temperature to low temperature
Heat flows from areas of low temperature to high temperature
Heat flows through invisible waves from one object to another
Heat flows through the rising and falling of particles with different density

Conduction, convection and radiation
Microwaves, sound waves and UV radiation
Conduction, convection and waves
Longitudinal, transverse and quantum waves
Sound is produced when
Something vibrates moving back and forth very quickly
