Two bottles of water are touching on a shelf in the refrigerator. The temperature for both is the same. This is known as which of the following? A.
initial temperature

B.
final temperature

C.
thermal equilibrium

D.
thermal energy

C

Explanation:

If there is no heat to transfer from one bottle to the other, then both bottles are at an equilibrium. This just means that they're both on the same thermal energy level.

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
