Expert Answer:
Q.1. - A block weighs 165 g in air and 130 g in water. Calculate the volume and specific gravity.
Solution -
Let the volume of block be V
By Archimede's principle,
mass of object in air - apparent mass when submergerd in water = density of water x volume of object
165 g - 130 g = 1 x V
V = 35 g
Specific gravity also known as relative density = density of object/density of water = mass of object in air/Volume of object/density of water
Thus,
Specific gravity = 165/35/1 = 4.7
