Here's why:
* Balances compare masses: Balances work by comparing the unknown mass of the object to a known mass (usually weights). This allows for accurate determination of the object's mass.
* Irregular shapes don't matter: A balance doesn't rely on the shape of the object, only its gravitational pull, which is directly proportional to its mass.
There are two main types of balances used in science:
* Triple beam balance: This type uses three beams with sliding weights to balance the unknown mass.
* Electronic balance: This type uses sensors to measure the force exerted by gravity on the object and displays the mass digitally.
Both types of balances are highly accurate and suitable for measuring the mass of irregularly shaped solids.
