Solution

Objects having more density than water sinks in it. [0.5 marks]

Copper utensil have more density than that of water. So it will sink in water. [1 mark]

Objects having less density than water floats on it. [0.5 marks]

Oil have less density than that of water. So it will float on water. [1 mark]
