h) Why did the steelworkers introduce the carbon into the metal? What role does it play and how does it work? i) Compare the densities of austenite and martensite. The following space-filling diagrams may help. Assume the unit cells are the same size. side of cube diagonal across face of cube Austenite Martensite j) Improved gas mileage is an increasingly important goal in car construction. Gas mileage will increase as density: increases decreases side of cube side of cube

Amining crew extracted two diferent types of minerals from underground. Then, they transferred the same amount.of energy into both minerals. Why did mineralA change while mineral B stayed the same? Explan what happened to the molecules of beth minerals. mineral A. mineral A. phase; solid phase: liquid energy transferred mineral B. mineral B in phase: solid phase: solid before after

Supercooling  is:  a. a process in which liquid freezes at higher temperature than it's freezing point when left unstirred  b. a process in which liquid  becomes solid at  OoC   c. a process in which liquid freezes at lower temperature than it's freezing point when stirred  d. a process in which liquid freezes at lower temperature than it's freezing point when left unstirred
