Question

a sealed cooker made of steel of 500g volume of a 3 litre . will it sink in water or not ? density water is 1000 kg m-3

Answer 1

Mass = 500 g = 0.5 kg
Volume = 3L = 0.003 m³

Density of the sealed cooker
= 0.5÷0.003
=166.66 kg/m3

As the density of the sealed cooker is less than that of water so it will not sink in but it will float on water.
