they are both marine ecosystems
Theoretically, (provided that the water samples were of the same temperature), the teaspoon of salt would dissolve faster in the fresh water because the salt water is closer to its saturation point than the fresh water.
Oceans are large bodies of saltwater that cover the majority of the Earth's surface, while lakes are bodies of freshwater surrounded by land. Oceans are interconnected and have significant influence on global climate, while lakes are typically smaller and more isolated ecosystems. Oceans have tides and currents, while lakes do not have the same level of dynamic movement.
Objects that contain a higher density that water will sink, but if the same object has a lower density that saltwater, then it will float in salt water. And this also depends on the concentration of sodium ions present in the salt water. As the concentration of the sodium ions increase, the density of the salt water increases.
Fresh water tends to have no salt content. Fresh water is not ionized. Salt water is ionized with sodium chloride (salt). The average salinity of the oceans is roughly 35 ppt (parts per thousand).
Fresh water (of the same temperature) has the lower density ('lighter').
no it is not the same
Salt water needs to be much colder than fresh water to freeze because salt melts ice.
Basically yes; fully aquatic fish push water through their gills. This feature is the same in both freshwater and saltwater fish.
Saltwater intrusion is the movement of ocean water into fresh groundwater that causes contamination of the freshwater by salt. This is a process of nature and usually occurs near the coastlines where the fresh groundwater level approaches the same level as the sea.
The boiling point of salt water is higher than that of fresh water because the presence of salt increases the boiling point of a solution. Salt water requires more energy to come to a boil compared to fresh water at the same atmospheric pressure.
it depends on the circumstances. boat type, wind..... In a controlled environment where water temp,current, and wind are equal you will be faster in fresh water. this is because fresh water is less dense thus creating less resistance. on the other hand you float higher in saltwater which can also create less drag. However mathematically because of the resistance of saltwater you can calculate that you will be able to go faster in fresh water despite floating higher in saltwater. Its not much faster. I haven't calculated it but if I had to guess maybe 1-2% faster. A more dramatic example would be easier to understand. lets compare freshwater vs mud or somewhat diluted mud 50 50. its a lot easier to figure out which you will go faster in. My boat will practically sit on top of the mud. less drag right? This is what most people think saltwater does for them. How fast are you going to go in mud? Not hard to figure that out. there is too much resistance, you probably wont go anywhere. Apply this same logic to saltwater vs fresh and you can see that the more dense a solution is the more resistance it will have.
To create an estuary experiment, you will need a container, sand, saltwater, fresh water, rocks, and aquatic plants. Fill the container with a layer of sand, then add saltwater and fresh water on each side to simulate the mixing of salt and fresh water in an estuary. Place rocks and plants in the container to represent the habitat diversity found in estuaries. Observe how the water mixes and the plants and animals interact in this environment.
Salt water is salty because of chemicals that are dissolved in the water. The water is still H2O, the same as fresh water.
Theoretically, (provided that the water samples were of the same temperature), the teaspoon of salt would dissolve faster in the fresh water because the salt water is closer to its saturation point than the fresh water.
Salt water has a higher boiling temperature than fresh water so it would take longer than fresh water to heat up. this is because of the tendancy for H2O to 'cluster' around and cling to the salt molecules. This means that fresh water will evaporate faster than salt water (depending on the concentration).
At the same temperature fresh water evaporates faster.
Saltwater freezes slower than sugar water because the salt in saltwater lowers the freezing point of the water, requiring it to be at a colder temperature to freeze. Sugar does not have the same effect on the freezing point of water.
