A) 9 × 10?6/ºC
B) 6 × 10?6/ºC
C) 36 × 10?6/ºC
D) 27 × 10?6/ºC
Correct Answer: A
Solution :
greal = gapp. + gvessel So (gapp. + gvessel)glass = (gapp. + gvessel)steel Þ 153 × 10?6 + (gvessel)glass = (144 × 10?6 + gvessel)steel Further, (gvessel)steel = 3a = 3 × (12 × 10?6) = 36 × 10?6/ºC Þ 153 × 10?6 + (gvessel)glass = 144 × 10?6 + 36 × 10?6 Þ (gvessel)glass = 3a = 27 × 10?6/ºC Þ a = 9 × 10?6/ºCYou need to login to perform this action.
