1.	Which of the following is/are undesirable in heat-exchange systems handling liquid metals?(a) Deposition of impurities in cool areas(b) Resistance to heat transfer(c) Formation of brittle intermetallic compounds, resistance to heat transfer and deposition of impurities in cool areas(d) Formation of brittle intermetallic compoundsThe question was posed to me by my school principal while I was bunking the class.My doubt is from Environments topic in section Other Environments of Corrosion Engineering
Answer» The correct answer is (C) Formation of brittle intermetallic COMPOUNDS, RESISTANCE to heat transfer and deposition of impurities in COOL areas For explanation I would say: Conditions that are undesirable in heat-exchange systems handling liquid METALS: i. Deposition of impurities in cool areas ii. Resistance to heat transfer iii. Formation of brittle intermetallic compounds.
