Question

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

Answer 1

Step-by-step explanation:

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

• Now specific gravity is given by weight of object / weight of same volume of water
• Buoyancy or upthrust is an upward force exerted by a fluid that opposes the weight of an immersed object.
• Now Buoyancy is given by weight of displaced water = 150 – 120 = 30 grams
• Therefore Specific gravity of metal will be = 150 / 30  
•                                                                       = 5
