Question

a cube of side 10cm is heated from 27 c to 227 c the change in its total surface area if coefficient of linear expansion is 2*10^-6 per c
(c is Celsius)​

Answer 1

Answer:

Here percentage change in volume is given as, ΔV=γ×t×100

where, γ=3α

So, ΔV=3α×(T

)×100

ΔV=3×2×10

−5

×(473−273)×100=1.2
