A solution which contains ions is conductive, since the ions are electrically charged and can respond to a voltage. A solution which does not contain ions, but instead has intact molecules (such as sugar, to give a common example) is not very conductive. Of course, water always contains at least a small amount of ions since water itself dissociates into H+ and OH- ions, at least to a slight degree, so water is always at least mildly conductive. There are other solvents and other solutions which are entirely non-conductive.
Characteristics of solid silver are very good thermal and electrical conductivities.
Calcium chloride dissociates into Ca2+ and Cl- ions, which can conduct electricity in solution. On the other hand, barium chloride dissociates into Ba2+ and Cl- ions, which are less mobile in solution due to the larger size of the barium ion. This difference in mobility leads to variations in electrical conductivity between the two compounds.
Yes, indeed: one of the highest electrical conductivities of any known substance.
In metallic form, the best conductor of electricity at normal temperatures is known to be silver, but at sufficiently low temperatures, almost any metal becomes a superconductor, so that under such conditions the conductivities are all equal. In electrolytic conductance in water solutions, hydrogen cations are the best conductors in the sense of the highest specific conductance.Li
Different kinds of solids have surfaces of different shapes.
Different objects heat at different rates because they have different thermal conductivities. Thermal conductivity is a material property that determines how well heat can transfer through a material. Objects with higher thermal conductivities will heat up more quickly than those with lower thermal conductivities.
Yes. Different cloths are made of different materials - and different materials have different heat capacities and thermal conductivities.
Different metals have varying conductivities due to their atomic structure and the way electrons move within them. Generally, metals with more free electrons, such as copper and silver, have higher conductivities compared to metals with fewer free electrons, such as lead or iron. The presence of impurities or alloys can also impact a metal's conductivity.
Thermal and electrical conductivities are physical properties.

thermal conductivities, which dictate how efficiently heat is transferred through the material. Additionally, factors like composition, density, surface area, and heat capacity can influence how quickly an object heats up or cools down.
Thermal conductivity is a measure of a material's ability to conduct heat. It determines how efficiently heat can flow through a substance, affecting how quickly or slowly the material can transfer heat energy. Different materials have different thermal conductivities, impacting their ability to insulate or conduct heat.
The answer depends on what characteristic you wish to measure: its length, width, mass, temperature, reflectivity (albedo), thermal or electrical conductivities, and so on.
The thermal conductivity of hard core depends on the specific material composition. Generally, hard materials like metals have higher thermal conductivity compared to softer materials. For example, metals like copper and aluminum have high thermal conductivities, while materials like plastics have lower thermal conductivities.
