Not if the wood is uniform.
Density isn't determined by the size of the specimen but by its mass per unit of volume. An oak branch has the same density as the whole tree it came from--the weights are vastly different, but density is the same.
No. To calculate density you divide mass by volume (d = m/V) If you double the size of something (volume), then you are doubling the amount of it (mass). The whole reason for using density to compare things is because it is a property of the substance that does not change, regardless of quantity.
The density of a wood is 0.72g/cm3 what will be the mass off the wood with measures 30cm101010?
It depends of the piece of wood itself and the type of wood that it is.
The density of wood is 650 kg/m3.That depends on the species of wood. Balsa is very light, D ~ 0.2. Other woods are more dense. Any that float in water have a density less than 1. If it sinks the density is greater than 1.
no
False. Changing the size and shape of pieces of wood is a physical change because the wood's composition does not change.
depends on its size and the density of the wood.
greater density items wood tend to sink, they are heavier then items of less density with same displacement size
Density isn't determined by the size of the specimen but by its mass per unit of volume. An oak branch has the same density as the whole tree it came from--the weights are vastly different, but density is the same.
No. The wood that you made the chair out of is still wood, so it is just a physical change.
No. Density is an INTRINSIC property, and as such it does NOT depend on the size of the sample.
When wood corrodes it rots. The amount of time wood takes to rots depends on the wetness of the wood, density of the wood, and what the wood is. The location of the wood can also change how fast the wood will rot.
the density is in the middle of the wood chip
The density of hickory wood is .89.
Density = mass / volume As sample size increases, both mass and volume increase in the same ratio.
The wood is "lighter" (weighs less; has less mass) than the iron because of it's density. Iron has a greater density than wood, and density is defined as mass/volume, so having the same volume (size), the iron will have a greater mass.
