Option 1 states that the packet will float in both water and liid B. To determine whether this statement is true, we need to consider the relationship between density and buoyancy.

Buoyancy is a force that acts opposite to the force of gravity, allowing objects to float in a fluid. An object will float if its density is less than the density of the fluid it is placed in.

In the case of the packet in water, we are told that the density of water is 1 g cm-3. The mass of the packet is 800 g and its volume is 1 liter (1000 cm3). By dividing the mass by the volume, we find that the density of the packet is 0.8 g cm-3. Since the density of the packet is less than the density of water, the packet will float in water.

Next, we consider the packet in liid B, which has a density of 1.5 g cm-3. The density of the packet is still 0.8 g cm-3, which is less than the density of liid B. Therefore, the packet will also float in liid B.

Based on this analysis, option 1 is correct. The packet will float in both water
