No, the sample of mercury will sink in water because the density of mercury (13.6 g/cm3) is higher than the density of water (1 g/cm3), indicating that mercury is denser than water and will not float.
Yes, Saturn's mean density is only 70% of that of water.
No, the Earth would not float in a bathtub because the Earth is much more massive and dense than water. The force of gravity acting on the Earth's mass would pull it down into the water, causing it to sink.
If 20g of mercury oxide were heated, the combined mass of oxygen and mercury would be 20 grams.
If your mass was 82kg on Earth your mass would still be 82kg on Mercury.Your weight would be different, if you weighed 82kg on Earth you would only weigh 30.9kg on Mercury.
no, mercury is a substanable resource meaning non waterised substance so cannot float in water No, mercury is heavier than water. It can't float in water. It is actually a metal that is liquid at room temperature and for several degrees around that. That's why it's used in thermometers.
Egg float in water because the mass of the water is less than the mass of the egg.
We float or there is a possibility you can sink. You sink when you are heaver than the mass of the water. You float when you are lighter than the mass of the water.
Most materials will float in Mercury because it is so dense. A lump of Lead will float in a bath of Mercury. The well-known metals Gold, Platinum, Tungsten, Uranium and Plutonium are more dense than mercury and would sink. More specifically, any material having a density less than 13593 Kg/m3 will float in a bath of Mercury.
No, the sample of mercury will sink in water because the density of mercury (13.6 g/cm3) is higher than the density of water (1 g/cm3), indicating that mercury is denser than water and will not float.
Yes, Saturn's mean density is only 70% of that of water.
Because the mass of salt water displaced by the egg is equal to the mass of the egg (Archimedes' Principle). If the water were pure it would weigh less and maybe the egg would then sink because it could not displace its own mass of water.
Float
That depends on the object's density, not just on its volume. For example, the object you mention would float if it has a mass of less than about 3.7 gramms.
An object will float - on water for example - if its density is less than the density of water. Density = mass / volume.An object will float - on water for example - if its density is less than the density of water. Density = mass / volume.An object will float - on water for example - if its density is less than the density of water. Density = mass / volume.An object will float - on water for example - if its density is less than the density of water. Density = mass / volume.
The pumice is not very dense, if the mass of the volume of water displacement is greater than the mass of the rock it will float
If it is made of wood, it is very likely that it will float. The mass alone (89g) is not enough information to determine if something will float. You will also need to know the volume. Divide the mass (in grammes) by the volume in (cubic centimetres) to give you a value of grammes/cc Water has a density of 1g/cc. If the wood has a value less than this then it will float in water.
