Why can scientists say that there is no such thing as "cold"
What is heat flows, and if heat is lost we may feel a "cold" sensation i.e. our hands would feel cold if we were holding a glass of ice water because the heat from our hand would go into the glass. Cold is just a lack of heat, cold does not flow.
