A concrete slab has a length of 10 m on a winter night when the temperature is `0^@C`. Find the length of the slab on a summer day when the temperature is `35^@C`. The coefficient of linear expansion of concrete is `1.0 xx 10^(-5 @) C^(-1)`.

Text Solution

Verified by Experts

`l_(1) = 10 (1 +1 xx 10^(-5) xx 35)`
`= 10.0035 m`
