1. The problem statement, all variables and given/known data An object has a density of 1250 kg /m3 at 10◦C and a coefficient of linear expansion of α = 2.5 × 10−5 1 /K . What is the object’s density when the temperature is 25◦C? 2. Relevant equations V=βV0ΔT V(T)=(1+β(Δt))V0 3. The attempt at a solution How I got the answer is that I used V(T)=(1+β(Δt))V0 and substituted v=m/ρ and after some algebra gave me the correct answer of 1248.6 kg/m2 When I used the first equation I listed I didn't get the correct answer... I was just wondering what the difference is in the equations and when to use them Thanks in advance!
