Lava is also around 100,000 times more viscous than water (viscosity being the measure of a liquid's resistance to change in movement or shape). Put those two together, and the result is that a human body, which has a density of around 1,000 kilograms per cubic meter, is just not he...

Wood density, considered a heritable trait, is often associated with drought tolerance and can be a useful trait for tree breeders to select drought-tolerant provenances. Provenance trials are a useful tool to disentangle genetic variation from plasticity of adaptive traits among populations within ...
It's worth noting that the terms "hardwood" and "softwood"can be misleading, as they don't always accurately reflect the actual hardness of the wood. For example, balsa, a type of hardwood, is relatively soft, while yew, a softwood, is harder than some hardwoods. The classification is ...
A forest is an area of land dominated by trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing and ecological function. Wood The hard fibrous material that forms the main substance of the trunk...
A recognized property of a substance (even if the substance is a solid, liquid, or gas) is density. The simple use of density is to predict if a solid substance such as balsa wood will float or sink in a specific liquid. Density can sometimes be expressed...
Large Strength to Density Ratio Easily Recycled plastic recycling Why Use HDPE? According toone report,"Nonporous surfaces like plastic or glass are easier to clean than wood and thus better in terms of food safety. Wood is naturally porous, and those tiny fissures and grooves in wooden cutting...
