Newsela Assignment Unit 3 Heat & EMS 11-16-20 Periods 1 & 3

(A) Both only occur when currents are created by different densities

(B) Both only occur when there is contact between two solid objects.

(C) Both can involve solids or gases, and need the presence of insulators in order to occur.

(D) Both can involve liquids or gases, and need a temperature difference in order to occur.

(A) Thermal equilibrium stops the transfer of energy in just one direction when both objects reach the same temperature, but allows their particles to continue transferring that energy back and forth.

(B) Thermal equilibrium always transfers energy from the hotter object to the colder one, and increases the energy and speed of moving particles in both objects as the temperature decreases.

(C) Thermal equilibrium helps the transfer of energy between the particles of some materials better than others, but always stops the transfer of energy in materials like plastic and wood.

(D) Thermal equilibrium quickly transfers energy back to the particles of the object that was originally hotter, and requires that the particles in both objects have reached equal energy and density

(A) The image illustrates the temperature differences between hot and cold water using red and blue arrows familiar to most readers of the article.

(B) The image illustrates the circulation of hot water rising and cold water sinking during convection using the example that is described in the article.

(C) The image illustrates the effects of the heat transfer occurring with the air above an object in addition to the convection that is happening inside it.

(D) The image illustrates the way that the asthenosphere is heated from even hotter regions below it to create slow but massive convection currents.

(A) It uses colored stripes to demonstrate that UV light and X-rays are low-energy forms of light.

B) It indicates the reactions that take place within the human eye for visible light to be seen.

(C) It places different kinds of light on a spectrum to indicate the variations in their energy levels.

(D) It shows the differences in energy between light acting as a particle and light acting as a wave.
