The volume of a 500g sealed packet is 350cm3. Will the packet float or sink in water if the density of water is 1g/cm3 ? What will be the mass of the water displaced by this packet?

Answer:
METHOD 1
Density = mass / volume
Density of packet = 500 / 350
= 1.42 g/cm3
hence, as we know that if a body have higher density than the density of substance in which the body is going to immerse then the body will sink.
in this case density of packet is more than the density of water so, packet will sink
METHOD 2
Here mass of packet, M = 500g
Here mass of packet, M = 500gVolume of the packet, V = 350cm3
Here mass of packet, M = 500gVolume of the packet, V = 350cm3Density of packet, d = m/v = 500g/350cm3 = 1.428g/cm3
Here mass of packet, M = 500gVolume of the packet, V = 350cm3Density of packet, d = m/v = 500g/350cm3 = 1.428g/cm3Since the density of packet is more than the density of solution, packet will sink
Here mass of packet, M = 500gVolume of the packet, V = 350cm3Density of packet, d = m/v = 500g/350cm3 = 1.428g/cm3Since the density of packet is more than the density of solution, packet will sinkMass of water displaced = volume of packet* density of solution
Here mass of packet, M = 500gVolume of the packet, V = 350cm3Density of packet, d = m/v = 500g/350cm3 = 1.428g/cm3Since the density of packet is more than the density of solution, packet will sinkMass of water displaced = volume of packet* density of solution= 350 × 1.2
Here mass of packet, M = 500gVolume of the packet, V = 350cm3Density of packet, d = m/v = 500g/350cm3 = 1.428g/cm3Since the density of packet is more than the density of solution, packet will sinkMass of water displaced = volume of packet* density of solution= 350 × 1.2= 420 g
