Why can we float easier in the sea than in a freshwater lake?
The density of salt water is higher than fresh water.
A man first swims in seawater then in river water.Compare the weight of seawater and the riverwater displaced by him?
We know that the density of the sea water is more than the density of the river water. So, the weight of displaced sea water is more than the weight of displaced river water. This weight gives the upward Buoyant force to the swimmer. Thus, the apparent weight of the swimmer is less in the sea water. Hence he finds it easier to swim in the sea water.
Does salt water affect floating or sinking?
Salt increases the density of water, thus makes it easier to float.I've always had troubles floating while swimming in fresh water, but the difference when swimming in the sea is quite noticeable.There are many notes of people doing experiments with floating eggs with salt water versus fresh water.
What else besides an egg float in salt water and sinks in fresh water?
It depends entirely on the amount of salt in the water. Pure water has a density of 1 kg/L. Any item that is less dense than 1 kgL, will float. Items with a greater density will sink. As you increase the salinity of water, the density of the salt adds to the water's density. The Dead Sea, for example, has a high saline level (31%) and it's density is 1.24kg/L. An average sized person can easily float in these waters.
Why seawater has greater density then that of freshwater?
because it has a higher concentration of ions and minerals!!! ions and minerals play a vital role to make sea water more dense. secondly, the molecular mass: water: h(2) + o(16) = 18g/mol NaCl = n(23) + cl(35.5) = 58.5g/mol NaCl has a higher moleculer mass so there is higher density than water seen!
What are the density independent and dependent factors that affect sea turtles?
affect turtles
What factors affect the density of sea?
Temperature, salinity, and pressure.
What makes the sea water have density?
Sea water has density because it contains dissolved salts and other minerals, which increase its mass without significantly changing its volume. Additionally, temperature and pressure variations in the ocean can also affect the density of sea water.
What two factors affect ocean salinity?
Freezing point (more salt the lower the freezing point). Density (more salt, the heavier the water).
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.
The density of sea water increases as?
the density of sea water increases as salinity increases and temperature decreases
In general he density of sea water increases as?
depth and salinity increases density of sea water increases
Why sea water and freshwater do not have same density?
Sea water and fresh water does not have the same density because sea water has salt, which makes it more dense than fresh water Sea water and fresh water does not have the same density because sea water has salt, which makes it more dense than fresh water
Why do ship float better at sea than in fresh water?
Sea water has salt, and therefore a higher density.
List three factors that affect salinity in the ocean and three factors that affect ocean temperatures. Explain how each factor affects salinity or temperatures?
Three factors are evaporation and freezing of sea water.
Why can you float in sea water easier than freash water?
sea water has a higher density
What is the density of water at sea level?
At sea level, fresh water has a density of 1. 0 grams per milliliter. Seawater has a higher density than fresh water, 1. 025 g/ml.
