We would like to make a vessel whose volume does not change with temperature (take a hint from the problem above). We can use brass and iron ( βvbrass = 6 × 10-5/K and βviron = 3.55 ×10-5/ K) to create a volume of 100 cc. How do you think you can achieve this.

This is a long answer type question as classified in NCERT Exemplar
As difference in volume is constant
By considering the diagram
Let Vio , Vbo be the volume of iron and brass vessel at 00C
Vi,Vb be the volume of iron and brass vessel at 0C
be the coefficient of volume expansion of iron and brass.
Vio -Vbo= 100cc= Vi-Vb
Vi =Vio(1+ i )
Vb =Vbo(1+ b )
Vi-Vb = (Vio -Vbo)+
Since Vi-Vb= constant
Vio i= Vbo
Using above equations
Vbo = 144.9cc

(b), (c), (d) When the hot milk in the table is transferred to the surroundings by conduction, convection and radiation.
According to newton's law of cooling temperature of the milk falls of exponentially. Heat also will be transferred from surroundings to the milk but will be lesser than that of transferred from milk to surroundings. So option b, c, d satisfy.
