Ascientist designed a foam container to keep frozen foods from melting. which best explains how the foam works? a. it removes thermal energy from the air inside the container. b. it removes thermal energy from the frozen foods inside the container. c. it reduces the amount of thermal energy that is transferred from inside to outside the container. d. it reduces the amount of thermal energy that is transferred from outside to inside the container.

c

Explanation:

i got it on my test

explanation: in any substance/object, the particles inside it (atoms/molecules) constantly move in random directions and with random speeds (this motion is called brownian motion). as a result, the particles have some kinetic energy (which is proportional to the temperature of the substance).

explanation:

have a great day!

convex lenses are thicker at the middle. rays of light that pass through the lens are brought closer together (they converge). a convex lens is a converging lens. when parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus.
