Because it does not produce waste, thus it doesn't harm the environment. also renewable sources are infinite.

Answer:

Explanation:

Renewable energy such as solar energy, wind energy, geothermal energy and hydropower are inexhaustible and obtained from natural sources. This energy can be replenished. Whereas, the non-renewable energy sources such as coal and petroleum products are exhaustible energy. They cannot be replenished. It takes millions of years to form non-renewable energy. The non-renewable energy cause pollution but renewable energy is environment-friendly without being depleted. Therefore, renewable sources of energy better than non-renewable sources.

Cuanto cambia la entropía de 0.50 kg de vapor de mercurio [Lv: 2.7 x 10⁵ j/kg ] al calentarse en su punto de ebullición de 357°
lord [1]

Answer:

La entropía del vapor de mercurio cambia en 214.235 joules por Kelvin.

Explanation:

Por definición de entropía (S), medida en joules por Kelvin, tenemos la siguiente expresión:

dS = \frac{\delta Q}{T} (1)

Donde:

Q - Ganancia de calor, en joules.

T - Temperatura del sistema, en Kelvin.

Ampliamos (1) por la definición de calor latente:

dS = \frac{L_{v}}{T}\cdot dm (1b)

Donde:

m - Masa del sistema, en kilogramos.

L_{v} - Calor latente de vaporización, en joules

Puesto que no existe cambio en la temperatura durante el proceso de vaporización, transformamos la expresión diferencial en expresión de diferencia, es decir:

\Delta S = \frac{\Delta m \cdot L_{v}}{T}

Como vemos, el cambio de la entropía asociada al cambio de fase del mercurio es directamente proporcional a la masa del sistema. Si tenemos que m = 0.50\,kg,L_{v} = 2.7\times 10^{5}\,\frac{J}{kg} and T = 630.15\,K, entonces el cambio de entropía es:

\Delta S = \frac{(0.50\,kg)\cdot \left(2.7\times 10^{5}\,\frac{J}{kg} \right)}{630.15\,K}

\Delta S = 214.235 \,\frac{J}{K}

La entropía del vapor de mercurio cambia en 214.235 joules por Kelvin.

Which team sport utilizes judges to determine the points earned? Football Hockey Rhythmic Gymnastics Soccer
finlep [7]

Answer:

Rhythmic Gymnastics

Explanation:

In general, the judges in the sports tend to be in charge for correcting and controlling the breaking of the rules in the particular sport. They are allowed to punish the competitors in accordance with the breaking of the rule, or they are there in order to determine weather a point is regular or not. In the rhythmic gymnastics though, and sports similar to it, the judges have different role, as they are in charge of determining the points earned by the competitors. This is done in a manner where every judge gives certain amount of points, or grades, and when those are summed up, the competitors get their total points.
