A U-tube contains mercury with one limb at 0°C and the other at 100°C. The heights of the mercury columns are 60 cm at 0°C and 62 cm at 100°C. The coefficient of volume expansion of mercury per °C is :
detailed solution
Correct option is D
V=V0(1+γ∆T) Al=Alo(1+γ∆T) ⇒ 62=60[1+γ(100)] ⇒ γ=260(100)=3.33×10-4/C oTalk to our academic expert!
