Astudent using a styrofoam cup as a calorimeter added a piece of metal to distilled water and stirred the mixture. a) the initial temperature of 50.0 g of water was 25°c b) the initial temperature of 20.0 g of metal was 100 °c c) the final temperature of the water and metal was 32.0° c which statement correctly describes the heat flow in calories? [hint: ignore heat gained or lost by the calorimeter. no calculations are needed to be performed]

a. the water lost 1360 calories of heat and the metal gained 140 calories of heat.

b. the water lost 350 calories of heat and the metal gained 350 calories of heat.

c. the water gained 350 calories of heat and the metal lost 350 calories of heat.

d. the water gained 1360 calories of heat and the metal lost 350 calories of heat.

.C) True. Water is colder than metal, explains all cases

Explanation:

In calorimetry the heat lost by the hot body is equal to the heat absorbed by the cold body, if there are no losses by other means.

In this case, the anime cup does not absorb heat, so the heat that yields in hot metal to be equal to the heat absorbed by cold water

Let's analyze the final statements

.A) False. The heat must be the same

.B) False. In this case the metal must be colder than in water, but there is no data to know

.C) True. Water is colder than metal, explains all cases

.D) False. The heats must be the same

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.
