Question

The linear coefficient of thermal expansion of titanium is ___________ /°F.

(a) 6.1×10^6

(b) 9.5×10^6

(c) 4.3×10^6

(d) 12.7×10^6

The question was posed to me by my school principal while I was bunking the class.

My question is based upon Chemical Processes of Titanium topic in division Titanium and its Alloys of Aerospace Materials & Processes

Answer 1

Correct option is (c) 4.3×10^6

Explanation: The linear coefficient of thermal expansion of titanium is 4.3×10^6/°F. The linear coefficient of thermal expansion of other elements like aluminium is 12.7×10^6/°F and that of stainless steel is 9.5×10^6/°F.
