THERMAL CONDUCTIVITY
All gases conduct heat by varying amounts. If an object is heated and
the source of the heat is then removed, the object will eventually cool
down to match the ambient air temperature. This action occurs because
the ambient air surrounding the object carries the access heat into the
surrounding atmosphere. This principal is also the same for objects that
are cooler than the surrounding ambient air. Dissipation of heat into an air
atmosphere is known and is a predictable rate. However, if the ambient air
is replaced with an alternative gas like helium, the rate at which an object
cools down changes.
If the object mentioned above had its environment replaced with pure
helium it would cool down to the environment temperature about 6
times faster.
