I need it asap

unless marked otherwise. 1. Tor F. Secondary bonds are weaker than primary bonds. Atomic spacing in a solid depends on the temperature of the solid 2. TorF. Tor F. T he interatomic spacing is determined by the sum of the attractive and repulsive forces 4. Tor F. 5. tomic bonding does not strongly influence strength or mechanical response to stress. Density depends on atomic weight and the arrangements of atoms in a solid. An interstitial is the same as a vacancy in an atomic structure T or F. 6. TorF. Tor F. A mx of two compounds A and B will form a solid solution with a eutectic point. 8, T or F. Alloy atoms must have more than a 15% difference in atomic radius compared to the base metal in order to obtain complete miscibility. 9. Tor F. Plastic deformation can occur easily along a slip plane. 10. T or F. Cold working metals decrease tensile strength of the worked metal. 11. T or F. A stainless steel can have less than 50% Fe in it. 12. Tor F. Mechanical stresses do affect corrosivity of a steel structural member. 13. Tor F. Electroplating can be used to protect steel from corrosion. 14. Tor F. The purpose of painting metals is to protect them from corrosion 15. Tor F. A temperature transition occurs in low carbons steels at room temperatures. 16. Tor F. The nucleus consists of electrons and protons. 17. TorF. Metals, like steel, exhibit ionic bonding. 18. Tor F. Polymers consist of a combination of a metal ion and hydrogen in a chain. 19. Tor F. A ductile to brittle transition temperature for a material is found by performing mult Charpy tests for a sample at different temperatures. 20. TorF. Steel processing furnaces have been found as early as 1500 BO. 21. TorF. Wide flange beams are narrower than "I" beams. 22. Tor F. In structural applications, civil engineers try to control rather than stop corrosion. 23. TorF. Pure water is an excellent electrolyte. 24. Tor F. Barrier coatings, such as paint, on steel protect it from corrosion. 25. Tor F. Processing steel by rolling leads to differences in transverse and longitudinal elong 6 The hardness of a sample increases with
