How much will the temperature of a 250 g block of silver increase if 2000 cal of heat is added to it?

143.37 K or °C

We are given;

We are required to determine change in temperature for the block of ice.

Q = m × c × ΔT, where M is the mass of an object, c is the specific heat capacity and ΔT is the change in temperature.

In this case;

Q = 2000 calories

Mass = 250 g

specific heat , c of silver is 0.0558 cal/g°C

Therefore;

Rearranging the formula;

ΔT = Q ÷ mc

    = 2000 cal ÷ (250 g × 0.0558 cal/g°C)

    = 143.37 °C or K

The change in temperature is 143.37 K or °C

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.
