Consider an isolated system containing two blocks of copper with equal mass. One block is initially at 0°C while the other is at 100°C. They are brought into contact with each other and allowed to thermally equilibrate. The heat capacity for copper is found to be:.
Cp = 24.5 [J/(mol K)]
What is the entropy change of the system during the process?

wavelength variability is the right one

muscle endurance

explanation:

i can do 50 in a row ( but i get so tired after that)

wire in brush may conduct electricity from cell to drill and vice versa electrc shock possible

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
