A density bottle contains 104.5 degree centigrade of a liquid at 34 degree centigrade on heating it to 100 degree centigrade the mass of the liquid expelled is 4.5gms.Then find the coefficient of apparent expansion of liquid.

Let the density of the liquid in the density bottle be `d`
Then volume of the liquid at 34degree centigrade V1=md=104.5d
volume of the liquid expelled when it is heated to 100degree centigrade(V2-V1)=4.5d
Coefficient of apparent expansion of liquid=[V2-V1]/[V1*(100-34)]
=[4.5d]/[104.5d*66]
=0.000652458

let the density of the liquid in the bottle be d. Given , m1=104.5gms t1=34 degree centigrade m2=m1+4.5 =104.5+4.5 =109gms t2=100degree centigrade we know that the coefficient of apparent expansion=(V2-V1)/V1(t2-t1) d=m/V>v=m/d = (m2/d-m1/d)m1/d*(100-34) =(109/d-104.5/d)/104.5/d*(66) =(4.5/d)/6897/d =4.5/6897 =0.000652457 =0.0007/degree centigrade
