Question

Match the correction in Column I to its operation in Column II. $α$ is scale linear coefficient and $γ$ is mercury cubical coefficient. All coefficients refer to 0°C.

List - I	List - II
(I) physical column length from indicated h	(P) multiply by $1 + α Δ T$
(II) equivalent 0°C mercury height from physical H	(Q) divide by $1 + γ Δ T$
	(R) multiply by $1 + γ Δ T$
	(S) divide by $1 + α Δ T$

TestHub · Accepted Answer

Physical column H = h ( 1 + α Δ T ) because scale divisions expand: I-P. Cold equivalent height h 0 ​ = ( 1 + y Δ T ) H ​ because hot mercury is less dense: II-Q. A.
