What else can I help you with?
How does temperature of water affect the time it takes to freeze into ice cubes?
because it depens in the temperature of the ?
What 2 ways can you change density of water?
By cooling it below 4 degrees centigrade whereupon its density will decrease. By heating it above 4 degrees centigrade whereupon its density will decrease. Water is at its densest at about 4 degrees centigrade.
Does nickel float?
No, nickel does not float in water because it has a higher density than water. Any object with a higher density than water will sink.
What has a effect on water density?
Temperature, salinity, and pressure have significant effects on water density. As temperature increases, water density decreases because warmer water molecules are more spread out. Higher salinity increases water density since dissolved ions make the water heavier. Pressure also impacts density, with deeper water being denser due to the weight of the overlying water column.
Which has higher density salt water or fresh?
Salt water has a higher density than fresh water. Fresh water is only made up of two things, hydrogen and oxygen. Salt water is made up of hydrogen oxygen sodium and chlorine, which gives it a higher density.
What controls the density of sea water?
The main factors controlling the density of seawater are temperature and salinity. Colder water is denser than warmer water, and water with higher salinity is denser than water with lower salinity. Other factors, such as pressure and the presence of dissolved gases, can also influence seawater density.
What is the term for colder water will sink while warmer water rises?
The term for colder water sinking while warmer water rises is called thermal stratification. This phenomenon occurs in bodies of water where layers of different temperatures form due to variations in water density.
In ocean currents how are temperature and density related?
In ocean currents, temperature and density are directly related. Colder water is denser than warmer water, so in regions where the water is colder, it tends to sink and flow towards areas where the water is warmer. This movement of cold, denser water and warm, less dense water helps to drive the circulation of ocean currents.
Does the temperature of water affect the its density?
The warmer the water is the less dense it is but the colder it is the more dense it is. A2: therefore, warm water rises above cold water
How does water temperature affect buoyancy?
Water temperature affects buoyancy because colder water is denser than warmer water. Therefore, objects will float higher in colder water due to the increased buoyant force. Warmer water is less dense, causing objects to float lower in the water.
Is ice water with salt warmer or colder than plain ice water?
it is warmer
The density of ocean water increases when it?
Ocean water gets more dense as temperature goes down. So, the colder the water, the more dense it is. Increasing salinity also increases the density of sea water. Source: Science book.
Where would the lowest density of sea water be found?
The lowest density of sea water is typically found in the surface waters in tropical regions, where there is high temperature and low salinity. This is because warmer water is less dense than colder water, and water with lower salinity is less dense than water with higher salinity.
Why do more animals live in the colder oceans than in warmer oceans?
Colder oceans tend to have more nutrients due to upwelling and circulation patterns, supporting a richer food web. Additionally, colder temperatures allow for higher oxygen levels, which can support a greater diversity of marine life. Warmer oceans may have more competition for resources and higher predation pressure, limiting the number of species that can thrive.
Is water warmer once it has just been raining?
No. Cooler if anything because rain falls from higher, colder altitudes.
What 2 main factors determine the density of seawater?
The main factors that determine the density of seawater are temperature and salinity. Warmer water is less dense than colder water, while water with higher salinity is denser than water with lower salinity. These factors combined play a significant role in the distribution of density levels in the world's oceans.
How does salinity affect the density of the ocean water?
Dissolving salts in water increases the density slightly. Ocean waters have an average density about 2.5% greater than fresh water. The Dead Sea has a much higher density, somewhere roughly near 20% greater than fresh water due to its 30% salinity level.
