1.	The principle upon which a lactometer works is(a) viscosity(b) density(c) surface tension(d) presence of protein
Answer» Answer is : (b) density Lactometer is a device used for testing the purity of milk. It measures relative density of milk with respect to water, which is also called specific gravity. If the specific gravity of a sample of milk is within the approved ranges, the milk is pure. If it is not, then there is some adulteration in milk.
