The core is known as nucleus which is surrounded by atmosphere of frozen gases. Comets orbit the Sun in elliptical path and enter the system when their path is perturbed by the disturbance in nearby star.

¿la densidad de una solución es mayor o menor al agregar agua?

andreev551 [17]

Answer:

La densidad experimenta una disminución

Explanation:

Hola!

En este caso, debemos recordar que la adición de agua incrementa el volumen donde se encuentra un soluto disuelto, el cual posee una cantidad de materia constante. De este modo, sabiendo que la densidad es:

$\rho =\frac{m}{V}$

Al incrementar el denominador (volumen), la densidad experimenta una disminución, al estar en relación inversamente proporcional.

5. Calculate the decrease in temperature when 6.00 L at 20.0 °C is compressed to 4.00 L.

Kazeer [188]

Answer: 195.3 K

Explanation: Use Charles Law to get T2

Charles Law V1 / T1 = V2 / T2

Derive the equation to find T2

T2 = V2T1 / V1

Convert temperature into K

T1 = 20.0 °C + 273 = 293 K

Substitute the values:

4.00 L x 293 K / 6.00 L = 195. 3 K
