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}](https://tex.z-dn.net/?f=%5Crho%20%3D%5Cfrac%7Bm%7D%7BV%7D)
Al incrementar el denominador (volumen), la densidad experimenta una disminución, al estar en relación inversamente proporcional.
Muchos saludos!
Answer:
The temperature of the mixture is 60°C
Explanation:
We can write the energy of water as follows:
E = m×C×T
<em>Where E is energy in Joules, m is mass of water, C is specific heat of water = 4.184J/g°C and T is temperature</em>
<em />
Replacing fot both samples:
E = 20g×4.184J/g°C×30°C
E = 2510.4J
E = 40g×4.184J/g°C×75°C
E = 12552J
The total energy of the mixture is 12552J + 2510.4J = 15062.4J
Mass = 60g:
15062.4J = 60g×4.184J/g°C×T
60°C = T
<h3>The temperature of the mixture is 60°C</h3>
Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt. Speed (or rate, r) is a scalar quantity that measures the distance traveled (d) over the change in time (Δt), represented by the equation r = d/Δt.
