If a rock is hard to break, it likely indicates that it has high strength and durability. It could be made of a dense material or have a strong mineral composition. This characteristic suggests that it can withstand significant force or pressure without fracturing or crumbling easily.
The conduction of heat is the vibration of the atoms in the material. A solid's atoms are very close together, so that when a particle is heated and begins to vibrate, the other particles vibrate as well very quickly Hope that helped
Actually, hot, less dense material rises, and cold, denser material sinks. Denser material will be heavier (per unit volume) and gravity therefore pulls it down. Less dense material has buoyancy and rises. It's very logical.

All hot solids or dense enough gases emit black body radiation. Gases that are not very dense are are cold absorb particular wavelengths while gases that are not dense but are hot produce their characteristic emission spectrum.

Sand heated to a very high temperature.
Sand heated to a very high temperature.
an enclosed structure in which material can be heated to very high temperatures, e.g., for smelting metals.
Viscosity is the thickness or thiness of a fluid, Density is the space between particles.When a fluid is heated, it becomes less viscous(thinner) and the particles move far apart so it is less dense. Temprature affects density and viscosity.Something that is dense doesn't have to be viscous and vice versa.EX: Salt water is dense but not viscous.Honey is very viscous but not very dense
Glass, since glass is a very dense material it will take a while for the light to enter.
very very dense :)
Most of the rainforest is very dense, but the understory and canopy are both pretty dense. The canopy and the understory are both very dense but the undersrory is the most dense.
Wood is the raw material used to produce charcoal. The wood is heated up very hot with little or no oxygen. It burns off the impurities and leaves carbon.
