The diagram shows a cross- of a thermos. The vacuum between the outer and inner bottles is a space containing no air or other matter. Which statement best describes the purpose of the vacuum inside a thermos? A: It prevents heat loss through radiation, which requires matter to transfer energy.
B: It prevents particles from transferring thermal energy between the outer and inner bottles.
C: It increases heat loss through conduction between the outer and inner bottles.
D: It allows for more collision between the outer and inner bottles.

The answer is as follows in the photo

Answer (d) the universe had cooled enough for atoms to combine, protons and neutrons were too far apart to form nuclei;

Answer;

hot magma rises and pushes up toward the lithosphere, and as it cools it cycles back down toward the core to be heated again.

explanation; convection currents are the circular pathways taken by a fluid that enhances heat transfer by the process known as convection which occurs in fluids.convection currents transfer heat from one place to another by mass motion of a fluid. earth mantle is in a semi-liquid state and behaves like any other fluid, rising up from the bottom of the mantle after becoming hotter and less dense from heat of the earth's core, as the rock loses heat into the earth's crust it becomes cooler and more dense, then sinking back down to the core, then repeating the cycle.
