Melting and boiling point determination
WebThermal conductivity of Platinum is 72 W/ (m·K). The heat transfer characteristics of a solid material are measured by a property called the thermal conductivity, k (or λ), measured in W/m.K. It is a measure of a substance’s ability to transfer heat through a material by conduction. Note that Fourier’s law applies for all matter ... Webmelting point (about 1-2oC per minute) to ensure that the rate of temperature increase is not faster than the ability of the heat to be transferred to the sample being observed. At …
