Does a ship that enters a fresh water lake from the ocean sink more or rise more?Justify your answer
Answers
Answer:
The ship will sink more.
because in fresh water less buoyant force is applied as compared to salty water .
Explanation:
Explanation:
It will sink, and it is easy to remember which way. The weight of the ship (called displacement, for a very good reason) hasn't changed, and it will always displace an amount of water that weighs the same amount as the ship (see, a good reason).
Since fresh water doesn't have all the salts dissolved in it, a volume of fresh water weighs less than the same volume of seawater. Therefore the ship has to displace more fresh water to equal her weight, and the ship sinks in order to do that.
or
Fresh water being less buoyant would cause the ship to sink.
The difference in density is about 3% so you would expect ti to sit about 3% of its ocean draft lower when in the lake.
If it drew 20 feet in the ocean, it might be .6 foot lower or about 8 inches. Fortunately ships will be marked with Plimsoll lines to show exactly how much lower and you don’t have to calculate. You just have to know how to read it.
