Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the conduction law?Fourier's Law describes heat conduction through materials
2. What is the radiation law?The Stefan-Boltzmann Law quantifies thermal radiation emitted by a body
3. How does conduction move heat?Conduction happens when atoms touch each other and pass energy through the material. In solids, it uses vibrations and electrons to carry heat. The rate follows Fourier's Law.
4. What is convection and how does it work?Convection moves heat with liquids or gases that flow. Warm fluid rises and cool fluid falls, and fans or pumps can help it move faster. This is how a kettle boils or a room heater works.

Thermal equilibrium: A state where there is no net flow of thermal energy between systems.
Fourier's Law of Heat Conduction: Relates the rate of heat conduction to temperature gradient and material properties.
Stefan-Boltzmann Law: States that the total energy radiated per unit surface area of a black body is proportional to the fourth power of its absolute temperature.
Microfluidics: The study of fluid behavior in channels with dimensions in the micrometer range.
