How do changes in heat energy affect the density of earths mantle material
IF the density is low, then there will be an echo
IF the density is low, then there will be an echo
No!!!! The density of the material determines whether something will float or sink.
The denser a material, the better its conductivity. Gas is worse than solids.
No, size doesn't affect an object's shape because it's the same unit and material.
i do not know but do you know, a beaker is likea cup...
All else being equal, for the same material, the more dense it is (i.e. the less air it contains) the slower it will burn.There is no overall general rule relating density of different substances and their burn rate.
volume does affect the density because the formula of density= mass/ volume
thickness doesnt affect it. The higher the density of the material, the greater the speed of sound. e.g 330 m/s in air 1500 m/s in water 4500 m/s in solids
Light slows as it enters material with a higher density whereas sound waves speed up in materials of higher density. Light bends towards the "normal" as it passes from a less dense medium to a higher density medium ie air into glass. Both sound and light can be reflected from surfaces.
Yes, water density will affect an object's ability to float.
