Websmooth cooling curve. Medium. Open in App. Solution. Verified by Toppr. Correct option is . A. sharp melting point. B. anisotropic character. Crystalline solid have definite shape and arrangement and fixed melting points usually very high. Crystalline solids are anisotropic because properties of crystalline solids are different when viewed from ... WebMelting Point and Freezing Point. Pure, crystalline solids have a characteristic melting point, the temperature at which the solid melts to become a liquid.The transition between the solid and the liquid is so …
WebNevertheless, cooling viscous liquids fast can avoid the crystalline solid form leading to the amorphous solid or glassy (vitreous) state (Debenedetti and Stillinger, 2001). WebB-On cooling curve (Temperature/time curve) show the behavior of crystalline and non- crystalline materials. Rhodium (Mw 103g/m) has an atomic radius of 0.1345 nm and a …
WebAll pure crystalline solids, including metals, have the property of melting and freezing at a single temperature. If a pure metal is melted and allowed to cool slowly, its cooling curve, i.e. temperature vs. time behavior will resemble those labeled A and D in Fig. 3. WebSolution. We start with the known volume of sweat (approximated as just water) and use the given information to convert to the amount of heat needed: 1.5 L × 1000 g 1 L × 1 mol 18 g × 43.46 kJ 1 mol = 3.6 × 10 3 kJ. Thus, 3600 kJ of heat are removed by the evaporation of …
