The melting point of ice is 0 °C (32 °F, 273 K) at standard pressure; however, pure liquid water can be super cooled well below that temperature without freezing if the liquid is not mechanically disturbed. It can remain in a fluid state down to its homogeneous nucleation point of approximately 231 K (−42 °C). The melting point of ordinary hexagonal ice falls slightly under moderately high pressures, but as ice transforms into its allotropes (see crystalline states of ice) above 209.9 MPa (2,072 atm), the melting point increases markedly with pressure, i.e. reaching 355 K (82 °C) at 2.216 GPa (21,870 atm) (triple point of Ice VII).A significant increase of pressure is required to lower the melting point of ordinary ice ---the pressure exerted by an ice skater on the ice would only reduce the melting point by approximately 0.09 °C (0.16 °F).

The density of water (in kg/m3)
at various temperatures in degrees Celsius
The values below 0 °C refer to super cooled water.
If the density of a substance is greater than the density of water, it will sink in water. If the density of a substance is less than the density of water, it will float on water.
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.
To calculate the relative density of a substance, you divide the density of the substance by the density of water. The formula is: Relative Density Density of Substance / Density of Water. The relative density is a measure of how dense a substance is compared to water.
Paper clips have a density greater than the density of water.
That is the specific gravity of the substance.
If the density of a substance is greater than the density of water, it will sink in water. If the density of a substance is less than the density of water, it will float on water.
If you are in a physics class, the answer is to float it in water and determine its density. In real life, take it to a jewelry store.

yes. the density of a element will not change only the mass and volume will.
The density of water is 1.0
The density of water is 1.
It's actually pretty easy. If the density of the substance is higher than the density of water, the object will sink. If the density of the substance is lower than the density of water, the object will float. Be aware though that various substances may have dissolved into the water, thus changing its density. For example, seawater has a different density than fresh water.

No. As long as they're at the same temperature.
-- If the object floats in water, then its density is less than the density of water. -- If the object sinks in water, then its density is more than the density of water. -- If the object floats in air, then its density is less than the density of air. -- If the object sinks in air, then its density is less than the density of air.
The density of ice is lower than the density of water.
Paper clips have a density greater than the density of water.
