i do not no
higher crystallinity in a polymer = lower density
The movement so described is called diffusion. When particles of regions of higher density move to regions of lower density, they are said to diffuse.
The liquid of higher density will settle to the bottom.
Higher the temperature the lower the density
because at higher temperature the air become light i.e. density is lower , so it flows from higher density to lower density area.
If an object has lower density than the fluid then it will float. If it has higher density then it will sink.
no
The higher the density the lower the buoyancy.
The density of air decreases as altitude increases.
No, the density of gas is lower because the the force of attraction is minimum at gaseous state.
I meant lower linear density, but I can't change it. So for example for Aluminum the Linear density of [111] is lower than for [110] and that is again lower than [100]. But you notice that the modulus of elasticity is higher for [111] than for [110] and that again is higher than for [100]
