1.Rhodium has an atomic radius of 0.1345nm and a density of 12.41g/cm^3. determine whether it has an FCC or BCC crystal structure.
2.One cubic metre of nitrogen at 40 degrees Celsius and 340KPa is compressed isothermally to .2(m^3). What is the pressure when the nitrogen is reduced to this volume? What is the modulus of elasticity at the beginning and end of the compression?
