Determine whether each of the statements is correct:
Heat flow rate transfers heat through matter.
Heat current always flows from colder substance to warmer.
The greater the heat flow rate, the more heat passes through the substance in the shortest possible time.
The unit for heat flow rate is Joule per second (J / s) or watt (W).
The heat flow rate does not depend on the substance through which the heat passes.
The heat flow rate is independent of the body shape through which the heat passes.
Fluffy or woollen clothing reduces heat emitted by the body.
