HydrometerAnswer & Solution
Answer:
Lactometer
Solution:
A lactometer is a little glass
instrument that is used to check for the purity of milk by measuring its
density or to find out the content of the water in the milk or to test the
richness of the milk. It works on the principle of the specific gravity-the
more the amount of water in milk, the more the lactometer will sink in milk.
Whereas, the more the milk with cream, the less the lactometer will float.
