Question

The length of each side of a brass cube is 10cm at 15degree celcius.what is the increase in volume when it is heated to 60degree celcius?given alpha brass=1.9into10power minus 5 degree Celsius minus 1

Answer 1

Answer:

We want to determine the increase in volume if a brass cube with side length 10 cm is heated from 15o C to 60o C.

The coefficient of linear expansion of brass is, α=19×10−6 /K.

⇒ The coefficient of volumetric expansion of brass is γ=3×19×10−6=57×10−6 /K.

⇒ΔV=V0γΔT=(10)3×57×10−6×(60−15)=2.565 cm 3.

⇒ The increase in volume if a brass cube with side length 10 cm is heated from 15o C to 60o C is 2.565 cm 3.
