Why would seawater be a better conductor of electricity than river water?

Water is actually a weak insulator and does not transmit current well unless it has ions in it, like saltwater does. Seaweeds are limited in their abilities to conduct electricity per se, but as they come from saltwater, the salts still present on their "leaves" conduct relatively well.

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.
The property of seawater used in induction salinometers to measure salinty is?
Induction salinometers measure the electrical conductivity of seawater. At a fixed temperature, the conductivity is approximately linearly proportional to salt concentration. The nature of the salt makes a difference, and sea salt composition varies somewhat around the world. For chemical solutions other than seawater, conductivity generally increases with increasing concentration, but the factor relating conductivity to concentration depends upon the composition of the solution. For a given concentration of salt near room temperature, conductivity increases about 2% for each degree Celsius of temperature increase because the viscosity of water decreases as the temperature rises. For solutions of strong acids, the temperature coefficient is nearer 1%/ degree. (The mechanism of conductivity in strong acid solutions differs from that in salt solutions.) Temperature coefficients are smaller at elevated temperatures. Weird nonlinearities occur in aqueous solutions below 4 degrees C, as the water begins to freeze. The temperature coefficient of seawater also depends slightly on the composition of the seawater. Commercial induction salinometers which calculate temperature corrections assume some standard composition of seawater, such as that found in Copenhagen bay. This may yield errors for seawater which has been concentrated by solar evaporation, such as in the Red Sea, or seawater which has been diluted by river water or ice melt.
How is hydro electricity generated?
Hydroelectricity is electricity made from moving water. In a river dam you may spot generators. The water spins the propeller in the generator and generates hydroelectricity. 13% of hydroelectricity is made parts of Africa.
Why it is easy to swim in a swimming pool than river?
In a river,flowing water exerts a force on the swimmer. To cross the river or to swim upstream the swimmer has to overcome this resistive force. This requires spending a lot of energy. As there is no flow of water in a swimming pool, the swimmer does not have to overcome the resistive force as in river. Hence it is easier to swim in swimming pool than in a river.
What are China's three major rivers?
The Chang River (Yangtze River), The Huang River (Yellow River), and the Xi River.
Is water a conductor water or an insulator?
It depends. Pure water do not conduct electric current; on the other hand, we consider tap and river water as a conductor because of the ions of the decomposed materials in the water. Water transmits electricity, heat, and sound very well, so it is a conductor. An insulator would not transmit electricity, heat, or sound well.
What part of a river system is closest to the mouth of the river is?
Where freshwater mixes with seawater, and the river usually widens out, is the river estuary.
Why seawater lighter than river water?
sea water is less denser than river water.
If freshwater and seawater meet at the mouth of a river which one sinks and why?
Seawater is more dense than freshwater. Therefore the seawater would sink lower than the freshwater. Ships do indeed stay higher in seawater because of the higher density or specific gravity of seawater over freshwater
Which river supplies most of he north islands electricity?
Campbell River
Is the river used for electricity?
Yes, they can. If a dam is placed across the river, falling water over the dam can drive turbines which produce electricity.
Which river supplies most of the north islands electricity of nz?
cambell river
What was the purpose of the dams of the Nile River?
To control the river and flooding and produce electricity.
What is the river that supplies the most electricity for the north island in nz?
campbell river.......i think??
What is the meaning of brackish?
The official definition of the word brackish is "(of water) slightly salty, as is the mixture of river water and seawater in estuaries."
Can the Singapore River be harnessed to generate electricity?
yes?
