A certain amount of kerosene at $0^{\circ} C$ has mass $m_{0} = 1.6 kg$ . The same volume of kerosene at $6 0^{\circ} C$ has mass $1.5 kg$ . Determine its coefficient of thermal expansion.

Options:

Answer:

Solution:

For equal sampled volumes,
$\frac{ρ _{0}}{ρ _{60}} = \frac{1.6}{1.5}$
$1 + 60 γ = \frac{1.6}{1.5}$
$γ = \frac{1}{900}^{\circ} C^{- 1}$
