Fourier law and Newton's law of cooling are both related to heat transfer.

• Fourier's law states that the rate of heat transfer through a material is proportional to the temperature gradient across the material.

• Newton's law of cooling states that the rate of heat loss of a body is proportional to the difference in temperatures between the body and its surroundings.

• Both laws are used in various fields such as engineering, physics, and chemistry.

• Fourier's law is used to calculate...read more
