Answer:
The water (the substance) that passes through the filter paper is called the filtrate. If your mixture is a solution, such as salty water, then filtering will not separate the salt from the water. Instead, by heating the soluton the solvent (water) evaporates leaving the solid (salt) behind.

<u>Answer:</u> The final volume of the gas comes out to be 4 L.
<u>Explanation:</u>
To calculate the volume with changing pressure, we use the equation given by Boyle's law.
This law states that pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.
Mathematically,
(At constant temperature and number of moles)
The equation given by this law is:
![P_1V_1=P_2V_2](https://tex.z-dn.net/?f=P_1V_1%3DP_2V_2)
where,
are initial pressure and volume.
are final pressure and volume.
We are given:
![P_1=2.0atm\\V_1=3L\\P_2=1.5atm\\V_2=?L](https://tex.z-dn.net/?f=P_1%3D2.0atm%5C%5CV_1%3D3L%5C%5CP_2%3D1.5atm%5C%5CV_2%3D%3FL)
Putting values in above equation, we get:
![2atm\times 3L=1.5atm\times V_2\\\\V_2=4L](https://tex.z-dn.net/?f=2atm%5Ctimes%203L%3D1.5atm%5Ctimes%20V_2%5C%5C%5C%5CV_2%3D4L)
Hence, the final volume of the gas will be 4 L.
