A metal cube of length of 10.0 mm at `0^(@)C` is heated to `200^(@)C`. Given: its coefficient of linear expansion is `2xx10^(-5)K^(-1)`. The percent change of its volume is

0.1

0.2

0.4

1.2

Text Solution

Verified by Experts

The correct Answer is:

Percentage change in volume `=gamma t xx100`
`=3alpha t xx 100=300 alpha t=300xx2xx10^(-5)xx200=1.2`
