Since the scientist is studying the polar ice caps, his main focus is on the CRYOSPHERE.

A cryosphere (derived from the Greek word kryos) is the scientific term for the parts of the Earth's surface that are frozen which includes the snow, permafrost, ice on rivers, lakes, ice caps and more. There are two major cryosphere elements and these are the polar ice and the alpine glacier.

The polar ice is the regions of the Arctic and Antarctica. Although the two regions are different, both of these regions are dominated by cold conditions plus a presence of ice, snow and water. The key difference between the two is that the polar arctic is a frozen ocean surrounded by a continental landmass and open oceans. On the other hand, Antarctica is a frozen continent by surrounded oceans.

At a certain temperature, 0.900 mol of SO3 is placed in a 2.00-L container.

Goryan [66]

Answer:

Kc = 2.34 mol*L

Explanation:

The calculation of the Kc of a reaction is performed using the values of the concentrations of the participants in the equilibrium.

A + B ⇄ C + D

Kc = [C] * [D] / [A] * [B]

According to the reaction

Kc = [SO2]^2 * [O2]^2 / [SO3]^2

Knowing the 0.900 mol of SO3 is placed in a 2.00-L it means we have a 0.450 mol/L of SO3

0.450 --> 0 + 0 (Beginning of the reaction)

0.260 --> 0.260 + 0.130 (During the reaction)

0.190 --> 0.260 + 0.130 (Equilibrium of the reaction)

Kc = [0.260]^2 + [0.130]^2 / [0.190]^2

Kc = 2.34 mol*L

think about putting a glass of water on the counter, in the freezer, and on a hot stove how does the temperature of the water af

Shtirlitz [24]

The kinetic energy and the physical state of water depend strongly on the temperature;

Firstly, The kinetic energy of water on a hot stove is higher than that on the counter in the freezer; that the kinetic energy is directly proportional to the temperature according to the relation: $K = \frac{3RT}{2NA}$ ; where R is the universal gas constant, T is the temperature and NA is Avogadro number.

As the temperature increases, the speed of colliding molecules increases and the kinetic energy increases.

Secondly, The physical state of water depends on the temperature; water has three states (gas, liquid and solid) depends on the temperature.
If a glass of water is putt on the counter in the freezer, it will be converted to the solid state (ice).
And, as if it is putt on a hot stove, it will be vapor (gaseous state).
