Water and salt, since the salt has dissolved into the water, assumingly, and sand isn't dissolvable so it can't pass through. If the water were to dry up, then you'd get the salt back, then it won't be able to go through the filter
Volcanoes and earthquakes occur due to movement of the Earth's tectonic plates.
<h3>How volcanoes and earthquake occur?</h3>
Both volcanoes and earthquakes occur due to movement of the Earth's tectonic plates. They both occurs due to the heat and energy that is releasing from the Earth's core. Earthquakes can increase or fastens the volcanic eruptions through severe movement of tectonic plates.
Volcanoes eruption occurs when molten rock called magma rises to the surface. Magma is formed when the earth's mantle part melts due to higher temperature.
So we can conclude that volcanoes and earthquakes occur due to movement of the Earth's tectonic plates.

Answer:
51.54°C the final temperature of the calorimeter contents.
Explanation:
Molarity of HCl= 0.50 M
Volume of HCl= 150.0 mL = 0.150 L
Moles of HCl= n
Molarity of NaOH= 1.00 M
Volume of NaOH= 50.0 mL = 0.050 L
Moles of NaOH= n'
Since moles of NaOH are less than than moles of HCl. so energy release will be for neutralization of 0.050 moles of naOH by 0.050 moles of HCl.
n = 0.050
(1 kJ= 1000 J)
The energy change released during the reaction = 2800 J
Volume of solution = 150.0 mL + 50.0 mL = 200.0 mL
Density of the solution (water) = 1.00g/mL
Mass of the solution , m= 200 mL × 1.00 g/mL = 200 g
Now , calculate the final temperature by the solution from :
where,
q = heat gained = 2800 J
c = specific heat of solution = 
= final temperature = 
= initial temperature = 
Now put all the given values in the above formula, we get:
51.54°C the final temperature of the calorimeter contents.
