5. An aluminum block of mass 0.3kg at a temperature of 85°C is dropped into 0.2kg of water at 15°C. Calculate the final steady temperature attained by the block and the water. (ew=4200 and aluminum= 900) entered to the of water and the temperature of the water increased​

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.
