Slogan about an ore minerals are found mined and process
by human use

"Minerals the necessity of human use are extracted from ores."

Explanation:

An ore can be defined as a natural sediment or rock which comprises of one or more kinds of necessary minerals. The minerals typically comprises of either metals or non-metals. The ores are extracted from the deep earth layers by the mining process. The ores are refined and treated by smelting. In this process the heat is applied to the ores to extract the metals. The metals are of great economic importance without conducting mining and extraction processes no one can get metals. Metals are used for making cans, metal wires, gadgets and others.

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
