i ave a problem wit a questn,n i dnt if it wasn't wellsoved ni. .if yu have newskool physics by anyakoha,go to page44,example 4.4,pls luk am wella,i tnk sumtin is wrong with the solutn

here is d question

A density bottle holds 250g of liqid at 30•C and only 248.5g at 60•C. Find
a.the apparent and
b.the real cubic expansivity of the liquid,if the linear expansivity of the material of the bottle is @g, let @ be alfa

Soln
¥a is the apparent cubic expansivity and the formula for ¥a=volume of liquid lost or expelled/volume of liquid remaining x temperature rise
And mass is proportional to volume.
¥a,apparent cubic expansivity=mass lost or expelled/remaining mass x rise in temperature (¤)

The temperature rises from 30•C to 60•C and the mass changes from 250g to 248.5g dat is 1.5g of liquid is lost
And change in ¤=60-30=30
¥a=1.5/248.5 x 30=0.0002012K^-1

B. The real expansivity is ¥r,cubic expansivity is ¥ and apparent expansity is ¥a,so ¥=¥r-¥a, and ¥ is 3 times the linear exapnsion and u are given the linear expansion to be 0.000006K^-1
¥=3@=3 x 0.000006=0.000018
From the formula,¥=¥r-¥a
0.000018=¥r-0.0002012
¥r=0.0002192K^-1

kuderrich:
SEPARATING FUNNEL:
A mixture of Petrol and Water do not mix together to form a single liquid, b’cos they are non-polar and polar solvent respectively. They rather separate out into two distinct layers when they are added. A separating funnel is useful here; d lower denser liquid layer is tapped off, leaving d upper less dense layer in d funnel.

CHROMATOGRAPHY
Chromatography uses a solvent moving over a porous absorbent medium (e.g paper or gel) to separate a solute. They are widely used to separate coloured as well as colourless substance
******************

QUESTIONS
1.A mixture of kerosene and diesel oil can be separated by.............
2. A mixture of Naphthalene and Candle will be separated by..........
3. What property is used in choosing Fractional distillation as a separating technique for a mixture of fractions of crude oil?
4. Mention 2 differences between compound and mixture?
5. Which of the following is a mixture (a) Bronze (b) Ethanol (c) CO2

1. Separating funnel
2. Sublimation
3.Boiling points
4.(i) compounds are always homogeneous. While mixture can be homogeneous. o, r heterogeneous.
(ii) the constituents that make up a matter cannot retain their individual properties while constituents of mixtures retain their properties
5.Bronze(mixture of copper and tin)

Another question calculate the final temperature of 250g of water at 60¤C if added to 150g of water at 5¤C specific heat capacity of water =420j/kg ₹₹₹physics is sweet₹₹₹

Heat loss= heat gained
250 x 420(60-@)=150 x 420 (@-5)
105000(60-@)=63000(@-5)
