The weight does not determine if an object will float in water. If an object has a DENSITY that is more than the density of water then it will sink, if it's density is less than the density of water it will float.
To find the volume of the bottle, you need to subtract the weight of the water from the total weight of the bottle and water. Then, divide this difference by the density of water to find the volume displaced by the water and consequently the volume of the bottle.
The weight of the beaker with 40mL of water will depend on the density of the water and the material of the beaker. Water has a density of 1g/mL, so the weight can be calculated by multiplying the density by the volume. The weight of the beaker itself will need to be accounted for as well.
If an object has a lower density than water, it will float. If an object has a higher density than water, it will sink. This is because objects will displace an amount of water equal to their own weight, and if the weight of the water displaced is greater than the weight of the object, the object will float.
An object will float in water if its density is less than the density of water, which is 1 g/cm^3. This means that the weight of the object is less than the weight of the water it displaces, allowing it to float.
Objects with a lower density than water will float. This is because their weight is less than the weight of the water they displace, causing them to float on the water's surface.
A product will sink in water if its density is greater than the density of water. This means that the weight of the product is greater than the weight of the water it displaces, causing it to sink.
The unit weight of submerged soil: Submerged Density (kN/m3) = Saturated Density - Water Density Water Density = 9.81 kN/m3
The buoyant force acting on the solid in the liquid is 40 N, which is equal to the weight of the liquid displaced. The weight of the solid in water can be calculated by using the relative densities of water and the liquid (0.8) in the relation: weight in water = weight in liquid * (relative density of liquid / relative density of water).
Geologists reference a material's density in reference to it's weight. Density is the material's weight divided by the weight of an equal volume of water.
The density of water does not change when the volume changes. This is because density is a proportion of weight to volume. The density of water changes with temperature, but is approximately 1g/ml.
Because ice is solid and has a heavier weight that cause it to have higher density and as for water vapour, it is gaseous and has lower density due to not having any weight.
