The answer is right there in the question.
The density of any floating object is less than
that of the fluid in which it floats.
Not always - the density of a liquid may be greater or less than that of the solid form depending on the molecular structure and arrangement. For example, water is an exception as its solid form (ice) is less dense than its liquid form.
Usually yes; but depending on the metal, the density can be anywhere from less than one (kg/liter, i.e., the density of water), to about 20.
No.
Water's density is 1.If an object floats, it's density is less than 1.If an object sinks, it's density is greater than 1.Specific Gravity can be calculated as:(weight in air) / ((weight in air) - (weight in water))
no this is not true baby oil has more density than water.
True... warm water is less dense than cold water.
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.
No. Objects will only float in water with a density that is less than 1. This is not always true if another substance is in the water, such as salt.
Yes, that's correct. A ship floats on water because it displaces an amount of water equal to its weight. The density of the ship (mass divided by volume) is less than that of water, allowing it to float.
Not always - the density of a liquid may be greater or less than that of the solid form depending on the molecular structure and arrangement. For example, water is an exception as its solid form (ice) is less dense than its liquid form.
No.
It is true that water expands as it freezes, but the reason it floats on water is because the density of solid water (ice) is less than that of liquid water. And the density of ice is lower because of the expansion (same mass/larger volume).
Usually yes; but depending on the metal, the density can be anywhere from less than one (kg/liter, i.e., the density of water), to about 20.
No.
An object that floats in water is less dense than the water it displaces. This means that the weight of the water it displaces is greater than the weight of the object itself, causing it to float. Objects that float have a density less than 1 g/cm3.
Things sink in water when their density is greater than that of water. Water has a density of 1000 kg/m3, rock exceeds this by a significant amount. The principle at work is that things sink if they water tey displace weighs less than the mass of the object.
Because their density is less than the density of coke. And if that's not true of the object, then it sinks.
