Question
The coefficient of volume expansion of glycerin is 49 × 10–5 K–1. What is the fractional change in its density for a 30 °C rise in temperature?
Solution
Coefficient of volume expansion of glycerin, αV = 49 × 10–5K–1
Rise in temperature, ΔT = 30°C
Fractional change in its volume = ΔV/V
Relation between fractional change in volume and change in temperature is given by,
Rise in temperature, ΔT = 30°C
Fractional change in its volume = ΔV/V
Relation between fractional change in volume and change in temperature is given by,
