When the temperature of a metal cylinder is raised from 0.0°C to 110°C, its length increases by 0.22%. Find the percent change in density.

Volume of cylinder = pi*r*2*L

As, from the above formula, volume is directly proportional to length,

So, if we increase in length also increases in volume by 0.22%

we know

density = mass / volume

As, density is inversely proportional to volume it means increasing in volume decreases the density by 50.22%
