Q: Which law states that the rate of heat transfer through a material is proportional to the temperature gradient?

Solution: Fourier's Law of Heat Conduction states that the rate of heat transfer through a material is proportional to the temperature gradient.

Steps: 5

Step 1: Understand that heat transfer is the movement of thermal energy from one place to another.
Step 2: Learn that a temperature gradient is the difference in temperature between two points.
Step 3: Know that 'proportional' means that as one thing increases, the other thing also increases in a consistent way.
Step 4: Recognize that Fourier's Law of Heat Conduction describes how heat moves through materials.
Step 5: Conclude that according to Fourier's Law, if the temperature difference (gradient) is larger, the rate of heat transfer will also be larger.
