does a gallon of sea water weigh the same as a gallon of lake water or river water, or tap for that matter?

Question

I guess what I'm asking is, is the weight of fluids constant, or does a gallon of bleach weigh more/less than a gallon of water?

Answer 1

The weights of fluids varies. Sea water is heavier than lake water, which is why it's easier to float in the ocean. The gallon weights are still really close together but they do vary.

With other fluids, we have different weights. Aviation gasoline weighs in at 6.5 lbs per gallon; jet fuel is 7.0 lbs per gallon, many motor oils are 8 lbs per gallon. Further, these lbs-per-gallon vary with temperature as well.

Answer 2

The sea water is more dense and weigh more than the tap water. The bleach G. weigh more too.
There are some lakes with more salt content (in the water) than the sea. The Dead Sea is a lake, but the salt content is so high that nothing but bacteria lives there. A gallon of its water will weigh 30% nore than a gallon of tap water.

A Gallon is a volume. You can have a gallon of air or a gallon of mercury and the weigh of the second is about 23 pounds.

Answer 4

A gallon of sea water might be significantly heavier than lake or tap water, because of the salt content. The weight of a gallon sea water will also depend on the amount of salt dissolved in it.
In other words, the saltier the water, the heavier it is.

Answer 5

Sea water is marginally heavier than lake or river water, due to the salt and other minerals on it, and lake water is marginally heavier than tap.
The weight of a gallon of bleach is near to the one of the water gallon since bleach is almost always a solution in water, but the weight depends on the specific weight of the substance.

Answer 6

Fluids do have a constant weight. They don't like being compressed. So a gallon of water will weigh the same in many different situations (such as heating or cooling).

However....different liquids will weigh a different amount. For example, we can float on water, but not on gasoline.

Salt water is not water...but water with salt disolved in it. River water will have sand and mud in suspension (different from being disolved).

But basically because they are different things the weight will be different. How much different will depend on what is also in the water.

Salt water is heavies, which makes us float better in the sea. Most famously people float very easily in the dead sea because of its salt content.

Depends if you are using US gallons or English gallons. Either way it is easier to convert to metric units as 1 litre of water weighs 1Kilogram. So convert gallons to litres and your answer is the weight in kilos. Now convert your kilos into pounds or whatever weight you want and you have your answer.

Answer 9

Eat better. Eat foods found in nature. No foods made in a factory. None.
Get active. Everyday do something. Walk. Run. Dance. Whatever. Get a dog, take it for a walk. Play with your kids if you have any. Get moving.

Answer 10

No, the weight of the fluid depends on the molecular masses of all the species in the fluid. Different fluids have different weights depending on what they are made of.
