The change in density of mercury, when it is heated from 10^ C to 60^ C is (The coefficient of volume expansion of mercury is 18.2 10⁻⁵ ~K ⁻¹ )

Options

  1. A1.82 %
  2. B0.91 %
  3. C9.1 %
  4. D0.45 %

Correct answer

B. 0.91 %

Step-by-step solution

= m V = V V = V₀ Y T V₀ =Y T So, 100= Y T 100 aligned & =18.2 10⁻⁵ 50 100 & =0.91 % aligned
