If we pour water in basket filled with sand?

Question

If we have 6 liter basket filled with 10kg of sand of density
2kg/liter, and we pour 1 liter of water and the basket is full.

The sand will lose 5kg of weight due to buoyancy,
and total weight of the basket should become
(10kg - 5kg) + 1kg of water = 6 kg. How come?

Answer 1

You can't use the buoyancy argument. Regardless of whether the object (in this case sand) floats or sinks you are adding mass so the total becomes the sum of the individual masses. If the "basket" overflows it's more complicated.

Answer 2

This question really should be somewhere like "Games & Recreation > General - Games & Recreation" rather than Physics, but anyway, here is an answer:

The 6 liter porous (as baskets are wont to be) basket is sitting in a larger bucket or tub which in turn, is filed with water to the same level as the sand in the basket, on top of the sand, and above the water, and filling the remaining space in the basket, is a non-porous pan (or could be a plastic bag) of negligible weight, into which the 1 liter of water is poured.

Actually I lied, I said this was an answer, but really the question was: "How come?" not ,"find a ridiculous contrived explanation".
How come this question requires a ridiculous contrived explanation, I can not answer.

Answer 3

Here, you're talking Mass not Weight.
Adding 1 litre of water to the basket which, I hope, is leak-proof, you're adding an extra kg. The weight, in this case the Mass, will be 11kg (a full basket of 5L of sand and 1 L of water).
If the basket is porous, the water will run through and partially drain away leaving wet sand. This will still increase the original mass unless the porosity of the basket is enough for some sand to be lost too.
The question has too many if's and but's in it..

Answer 4

Buoyancy is the upward force on an object, commonly in a fluid. If the basket is FILLED as it says, when the water is added it will cause upward movement of the sand and since it is filled the sand would have to fall out of the basket. Otherwise, when the water was added and there was room for the water and all the sand, the total wheight would increase proportionally.

Answer 5

By your logic, submerging a 10 liter balloon in 9 liters of water (a fairly tight fit) by tying the balloon to the bottom of the bucket should cause the whole assembly to float away. The balloon, after all, will have a buoyant force of 10 kg (times g) pulling upwards on the string, but only 9 kg of water weighing it down. What are we forgetting? The10 kg of downward force the balloon exerts on the water whilst submerged. Likewise the wet sand will weight g times 11 kg

Answer 6

weight= mass*gravity gravity is constant so mass and weight will be directly proportional, you lose mass you lose wieght

regargless of the buyoncy the water has on the sand the water and the sand is still being pulled by gravity as if it we one object in the basket

think of jumping in the pool, yes you would weight less on a scale IN THE POOL, but if you had a scale to weight the pool the increase in weight would be you body weight

Answer 7

??????Because some water and sand will flow out of the basket??????

Baskets have holes!!!!!
