What causes difference in density?
A density difference can exist between two fluids because of a difference in temperature, salinity, or concentration of suspended sediment. Density currents in nature are exemplified by those currents that flow along the bottom of oceans or lakes.
Can two objects have the same mass but different densities?
Answer:Because mass and volume are independent, two objects with the same volume can have different masses. Therefore, the objects can have different densities. However, if two objects have the same mass and volume, they will have the same density.
What is the difference between high density and low density?
High density liners are thinner and less puncture resistant, usually found in a “natural” but not fully clear color. Although they aren’t as strong as their big brother, the low density can liner, they’re economical and great for office bins and trash cans that are used for tossing out paper and lightweight trash.
Do heavier objects have higher density?
Less Dense, More Dense If something is heavy for its size, it has a high density. If an object is light for its size it has a low density.
What causes the difference in density between HDPE and LDPE?
HDPE’s formidable structure gives it a higher density than LDPE. The forces of attraction between polymer molecules are strong.
How can objects have the same volume but have different densities?
Density is mass per unit volume, so if two objects have different masses but the same volume, they will have different densities. This is possible because the particles of different substances have different masses and pack differently together.
Why do some materials have higher densities than others?
Most metals have high densities. Temperature can affect the density of a substance, especially if the substance is a liquid/gas as this significantly changes the spacing between the particles within the substance (volume). The higher the temp, the greater the spacing (increase in volume) and therefore the lower the density.
Can a substance have the same density as another substance?
Thus to explain in layman terms, density is how much something weighs, compares to how much space it takes up. It is constant for every material. Mind you, two different materials of same shape and size do not have the same density.
What makes a substance have a high density?
These are the two main determinants in the density of a substance. A substance with a high density could have both high mass atoms (high mass), and atoms that are closely packed (low volume) resulting in a high value for mass/volume. A good example is metals.
