Question

What is the specific gravity of the metal if the piece of metal weighs 150grams in air and 125grams in water​

Answer 1

Answer:

6

Step-by-step explanation:

Given: The piece of metal weighs 150 grams in air and 125 grams in water.

To find: The specific gravity of the metal.

Solution:

Specific gravity, is the ratio of the density of a substance to the density of a given reference material.

As we know that the formula for specific gravity is given by:

          weight of object / weight of same volume of water

Also we know that buoyancy/ upthrust is an upward force that fluids exerts which opposes the weight of an immersed object.

So, buoyancy is given by weight of displaced water

          = 150 – 125

          = 25 gm

Therefore Specific gravity of metal will be

          = 150 / 25  

          = 6

Answer:

          The specific gravity of the metal is 6.
