what is the relationship of density temperature and salinity in seawater?
97288
Salinity and density share a positive relationship. As density increases, the amount of salts in the water—also known as salinity, increases. Various events can contribute to change in the density of seawater. Salinity can decrease from the melting of polar ice or increase from the freezing of polar ice.

Density is simply a ratio between the mass of a sample and it's volume. Specific Heat is a measure of how much thermal energy is required to raise the temperature one degree Celsius of one gram of the material. There is no correlation between the two quantities.

Answer: Density is defined as mass per unit volume. Specific gravity is the density of a material at a certain temperature divided by the density of water at a certain temperature; the reference temperature is usually 20 degrees Celsius. Pycnometers measure volume.

Density is the only thing affecting whether something floats or sinks. If an object has a higher density than the fluid it is in (fluid can mean liquid or gas), it will sink. If it has a lower density, it will float. Density is determined by an object's mass and volume.

Since g and the weight of the object Wobject are fixed, an increase in density means a decrease in the submerged volume, for the equation to hold. For a floating object, the buoyancy force is equal to the gravity force on the object. Hence, the buoyancy force doesn't change with a denser fluid.

Changes in salinity could also affect water currents because saltwater is denser than fresh water and sinks. Warmer air can absorb more water than cooler air, so as the climate warms, more water can evaporate into the air. ... That intensifies the water cycle on both ends of the spectrum.

Density is directly proportional to pressure and indirectly proportional to temperature. As pressure increases, with temperature constant, density increases. Conversely when temperature increases, with pressure constant, density decreases.

Many grow optimally in water temperatures between 73° and 84° Fahrenheit (23°–29°Celsius), but some can tolerate temperatures as high as 104° Fahrenheit (40° Celsius) for short periods. Most reef-building corals also require very saline (salty) water ranging from 32 to 42 parts per thousand.

The temperature of the deep ocean drops gradually with depth. As saline water does not freeze until it reaches −2.3 °C (colder as depth and pressure increase) the temperature well below the surface is usually not far from zero degrees.”

Deep ocean currents (also known as Thermohaline Circulation) are caused by: The density of sea water varies globally due to differences in temperature and salinity. Surface water is heated by the sun, and warm water is less dense than cold water.

The density of an object determines whether it will float or sink in another substance. An object will float if it is less dense than the liquid it is placed in. An object will sink if it is more dense than the liquid it is placed in.

The density of water is approximately 1 kG/liter, depending on temperature. ... Therefor, 5kG oil > 5 liters oil. 5kg of o. The density of water is approximately 1 kG/liter, depending on temperature.

Ocean waters are salty and contain minerals and dissolved gases. They also have a high heat capacity and vary in density depending on temperature and salinity.

Temperature is the measure of heat. Density is the measure of how closely any given entity is packed or it is the ratio of the mass of the entity to its volume. The relation between density and temperature is inversely proportional. Change in density will be reflected in a change in temperature and vise-versa.

What is Electrical Conductivity/Salinity/TDS? contributors to conductivity, although they are very important biologically. Salinity is a measure of the amount of salts in the water. Because dissolved ions increase salinity as well as conductivity, the two measures are related.
