271

What happen to the mixture of marbles and wood chips into the water?
When the mixture of marbles and wood chips is added to the water, the marbles will sink to the bottom of the container since they have a higher density than water. The wood chips will float on the surface since they have a lower density. The marbles will settle at the bottom, and the wood chips will remain floating on the water.
What is the result when marbles are added to a beaker of salt?
The marbles will pulverize the salt crystals so much that the salt looks like a powder but the salt has actually been reduced to very small crystals.
Why did an egg float when the salt is added to the water?
When salt is added to water, the density of water increases. Therefore the density of egg becomes less than the density of water therefore it begins to float in water.
Why does water's density decrease after potassium chloride salt is added?
The water density doesn't decrease.
What happens to the density when heat is added?
When heat is added to a substance, it increases the kinetic energy of its particles, causing them to move faster and spread out. This leads to an increase in volume and a decrease in density since density is mass divided by volume.
Why does the density of water increase when salt is added to it?
Density = Mass/Volume As salt(mass) increases and the volume remains the same, density also increases.
There are red and blue marbles in a jar one-third of the marbles are red if another marble is added to the jar then 3 8 of the marbles will be red how many marbles are blue?
Depends on what the question is actually saying:If the "3 8" is 38 (thirty eight):Let R = number of red marbles to begin with.Let B = number of blue marblesGiven two facts:R = (1/3)(R+B)R+1 = 38. (This assumes it's a red marble added)2nd equation gives R = 371st equation gives B = 2R = 2*37 = 74 blueIf the "3 8" is 3 over 8 (3/8 or three eighths):If a non-red marble is added, the problem is unsolvable as 3/8 is greater than 1/3, but with more marbles and the same number of red marbles, the fraction of red marbles will be less than 1/3. Thus it is assumed that a red marble is added:Let M be the number of marbles in the jar, and R be the number of red ones, then:1/3 M = R -- one third are red3/8 (M + 1) = R + 1 -- when an extra red marble is added, 3/8 of the marbles are now red marblesSubstituting R from the first equation into the second equation gives and solving gives:3/8 (M + 1) = 1/3 M + 1→ 9/8 (M + 1) = M + 3→ 9(M + 1) = 8M + 24→ 9M + 9 = 8M + 24→ 9M = 8M + 15→ M = 151/3 are red → 2/3 are blue→ 2/3 x 15 = 10 are blue................................................................................................................................Another Answer:1/3+1/24 = 3/8 It doesn't how many red marbles are added because now there are 24 but before there were 23 which is 1/3 of 69 of which 2/3 are 46 blue marbles.
What is the relationship between the density of an aqueous solution and its composition?
The density of an aqueous solution is directly related to its composition. The more solute (substance dissolved in the water) that is added to the water, the higher the density of the solution will be. This is because the added solute increases the mass of the solution without significantly changing its volume, resulting in a higher density.
When water vapor is added to the air the density of the air is?
When water vapor is added to the air, the density of the air decreases. This is because water vapor molecules are less dense than dry air molecules.
What happens to the density of water when shaved ice is added to water to make it a slushy?
-- The average density of the entire contents of the container decreases,because the density of the shaved ice is less than the density of the waterto which it was added.-- The density of the water alone increases steadily as it cools to 4°C (39°F),then decreases as the water cools further to a lower temperature.

Why is it that when you add pressure to a bottle it increases its mass?
When pressure is added to a bottle, it compresses the air inside, increasing its density. This makes the bottle heavier as the air exerts more force on the walls of the bottle due to increased pressure. The increased mass is due to the added weight of the compressed air inside.
