Highest density of water
WebThe density of seawater is a function of temperature, salinity, and pressure. Because oceanographers require density measurements to be accurate to the fifth decimal place, manipulation of the data requires writing many numbers to record each measurement. Also, the pressure effect can be neglected in many instances by using potential temperature. WebAnswer (1 of 5): That would depend upon to whom it was important. No, really, that’s the answer. Let’s say I’m traveling east and run smack dab into the Atlantic Ocean. I need to build something that will float to keep going. If I build that thing out of something that has greater density than w...

Web17 de fev. de 2016 · Density of Earth: Earth has the highest density of any planet in the Solar System, at 5.514 g/cm 3. This is considered the standard by which other planet’s densities are measured. In addition ... Almost all known substances undergo thermal expansion in response to heating, meaning that a given mass of substance contracts to a low volume at low temperatures, when little thermal energy is present. Substances, especially fluids in which intermolecular forces are weak, also undergo compression upon the application of pressure. Nearly all substances therefore reach a density maximum at very low temperatures and very high pressures, characteristic properties of the solid
