The coefficient of volume expansion of a liquid is `4.9xx10^(-4)K^(-1)`. Calculate the fractional change in its density when the temperature is raised by `30^(@)C`.

Explanation

To solve the problem of calculating the fractional change in density of a liquid when its temperature is raised by 30°C, given the coefficient of volume expansion, we can follow these steps:

### Step 1: Understand the Coefficient of Volume Expansion
The coefficient of volume expansion (γ) is given as \(4.9 \times 10^{-4} \, K^{-1}\). This coefficient indicates how much the volume of the liquid will expand per degree change in temperature.

### Step 2: Calculate the Change in Volume
The change in temperature (ΔT) is given as \(30°C\). We can use the formula for volume expansion:
