A fluid ounce of water weighs slightly more than a dry ounce (1 fluid ounce of water weighs 1.043 dry ounces). Therefore a fluid ounce of water is heavier than a dry ounce of flour (or anything else for that matter).
Note that a fluid ounce of something else might NOT be heavier. A fluid ounce of lead is much heavier than a fluid ounce of feathers!
Chlorine gas is less dense than water, so it will float on top of water if the two are in contact.
In a mixture of oil and water, the two will separate with the oil on top. If the water has enough solute in it (salt, sugar), the egg will float in the water, but not above the oil. An egg is denser than fresh water, but less dense than salt water. It is denser than most oils.
Kerosene and turpentine are less dense than engine oil. So is water and rubbing alcohol and other common liquids.
Ice is less dense than water, that's why it floats.
No, lithium is less dense than water, so it will float on the surface of water.
Dense water sinks in comparison to less dense water.
Less dense. Sifting is usually done before measuring so there is less flour in the finished product. There are other factors that change the density of the product, but for the flour's part, sifting would make it less dense.
no
Ice is less dense than water
It is less dense than water if there might be spaces between the small parts of the flour if no objects can be touching and the total density is slightly less than the density of the object and we'll be slightly increasing the volumes when calculating when repulsion isn't high
A wooden block can be less dense than water.
no beacause a rubber duck floats and if an object floats in water, is is less dense than the water if it sinks it is more dense
If more dense, it will sink when put into water; if less dense it floats.
Chlorine gas is less dense than water, so it will float on top of water if the two are in contact.
Oil IS already less dense than water.
Easy, put a fruit in water and if it floats it is less dense than water.
No. Ice is less dense than water. Because ice is less dense it displaces less water and floats. Water is most dense at 4o C. any change in temperature, either up or down, lowers the density.
