Answer:

Separation method for various ingredients are

1. Paneer from curdled milk. - Filtration

2. Chalk powder from water. - Filtration

3. Sand from salt solution. - Evaporation

4. Saw dust from water. - Skim off, sieve or filter

5. Tea leaves from brew. - Filtration.

Explanation:

By the help of a muslin cloth the paneer is separated from the curdled milk, the process is called as the filtration. The paneer will remain in the cloth and curdled milk will be removed. Separation of chalk powder from water is very easy by the process of filtration, after the filtration the chalk powder retentate and the filtrate obtained is the water in absence of chalk. Salt and sand water separation can be done with the help of evaporation. Separation of the saw dust from water takes place by the method of sieving or sedimentation. The tea leaves are separated from brew by filtration.

A student found the mass of an object to be 26.5 g. To find the volume, the student submerged the object in a graduated cylinder

KonstantinChe [14]

Answer: The density of the object is 1.10 g/ml

Explanation: Density of object = ?

Mass of object = 26.5 g

Volume of object = volume of water displaced = 24.1 ml

Putting values in above equation, we get:

$Density: \frac{26.5g}{24.1ml} = 1.10g/ml$

Thus density of the object is 1.10 g/ml
