Detailed explanation-1: -Two pan balance is commonly used for measuring mass in shops. It compares the sample mass with a standard reference mass. The pans rest on top of the beam and can be conveniently placed on a table top.

Detailed explanation-2: -In simple terms, a balance measures mass, while scales measure weight. So if you bring a balance and a scale to the moon, the balance will accurately give you the mass of, say, a moon rock, whereas the scale will be affected by the gravity. A balance determines mass by balancing an unknown mass against a known mass.

Detailed explanation-3: -A double pan balance measures weight because it is measuring the gravitational force on the sample compared to the gravitational force on a standard weight. A triple beam balance measures the gravitational force on the sample that is to say the weight.

Detailed explanation-4: -Balances Measure Mass Balances are instruments that measure mass (basically the amount of matter in something). A true balance measures mass directly by comparing the unknown mass to a known mass, a process that is not affected by changes in gravity.

Detailed explanation-5: -A Top Pan Balance is used mainly for rough weighing for preparation of reagents and stock solutions where slight weight variations do not have significant influence on the result of analysis.
