Questions & Step-by-Step Solutions

The rate of heat transfer by conduction is directly proportional to the area and the temperature gradient. This is described by which law?
  • Step 1: Understand that heat transfer can happen in different ways, one of which is conduction.
  • Step 2: Know that conduction is the process where heat moves through a material.
  • Step 3: Learn that the rate of heat transfer depends on two main factors: the area through which heat is being transferred and the temperature difference (or gradient) between two points.
  • Step 4: Recognize that there is a specific law that describes this relationship.
  • Step 5: Identify that this law is called Fourier's Law of Heat Conduction.
  • Fourier's Law of Heat Conduction – This law describes how heat transfer by conduction is proportional to the area through which heat is being transferred and the temperature difference across that area.
