The coefficient of volume expansion of glycerin is 49x10⁻⁵K⁻¹. What is the fractionalchange in its density for a 30°C rise in temperature?
Question
Solution 1
The coefficient of volume expansion (β) is given as 49x10⁻⁵K⁻¹ and the change in temperature (ΔT) is 30°C.
The fractional change in volume (ΔV/V) due to a change in temperature can be calculated using the formula:
ΔV/V = β * ΔT
Substituting the given values:
ΔV/V = 49x10⁻⁵K⁻¹ * 30K = 0.0147
