One of the laws of physics is that energy always flows from
warmer to colder areas. This is called conduction: Heat is
conducted away from hot objects and towards cold objects. For
example, when you sit down on a chair, heat flows from your body
into the chair. Then if you stand up and touch the chair cushion
a few minutes later, it will feel warm. This happens because of
molecular movement. When you sit down on the chair, your body
heat causes the molecules in the chair to start moving faster.
Once they start moving, they hit other molecules nearby until
all of the molecules near the top of the seat are moving and
transferring heat throughout the entire object. Heat conduction
only works through direct contact of solid objects. An example
of this in your home would be in your flooring. If your floors
are warm or heated, they will help warm up any furniture,
carpets, or other objects touching the floors, which will in
turn stabilize the heated temperature you've set for your rooms.
