Question

the length of each side of a brass cube is 10cm at 15 degree celcius.what is the increase in volume when it is heated to 60degree celcius?given alpha brass is equal to 1.9into10power minus5degree celcius.

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
