Heat transfer is a credital concept in fyzics that explicis how thermal energiy moves beween een objects and with in materials. Understanding thee principles behind heat transfer helps in designing accessient systems in currenering, environmental science, and everyday applications.

Fourier 's Law of Heat Conduction

Fourier 's law deskripbes how heat flows trofgh a material due to a temperature gradient. It states that that thee heat transfer rate is proporal al to thee negative of thee temperature gradient and thee material' s thermal directivity.

Te especsion is:

Q = -k A (dT / dx)

Newton 's Law of Cooling

Newton 's law of cooling explicains how thee temperature of an object changes over time when it traveres heat with its compleoundings. Thee rate of heat loss is proportal tol te temperature difference e between thee object and te environment.

Te law is expressed as:

dT / dt = -h A (T - T _ env)
