Answer 2

❄️ Required answer:-

☘️ a) Find out the device that is used to measure the quantity of water in milk?

→ Lactometer

More information :

Lactometer are used for milk purity checking. It is a cylindrical vessel made by blowing a glass tube. One side of glass tube looks like a bulb with filled by mercury and another site is thin tube with scaled.

☘️ b) What will be the reading when a hydrometer is dipped in water?

→ 1

More information:

Viscosity and density are two independent physical properties of a fluid. Hence an increase in density will not change the amount of drag experienced. However an increase in viscosity will affect it.

☘️ c) Find out the relative density of brine solution having density 1025 kg/m³?

→ 1.024

Explanation:

$\sf \: Relative \: \: density = \dfrac{1024}{1000} \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \underline{\boxed{ 1.024}}$

☘️ d) In which liquid will the hydrometer sink deeper? In water or in kerosene?

→ Kerosene

More information:

In low-density liquids such as kerosene, gasoline, and alcohol, the hydrometer will sink deeper,
