35. Solving a chemistry problem
3. How many times does the particle surface increase as a result of crushing a silver cube with an edge length of 0.5 cm to cubic particles with an edge length of 5×10-6 cm. The density of silver is 10.5 g/cm3. Calculate the surface energy after crushing, if the surface tension of silver is 1140∙10-3 J/m2.
