Question

The original volume of a liquid having expansion coefficient of 9.5 x 10-4 / ◦C was 4 litres. When heated it increased its volume by 190 ml. Calculate the rise in temperature of the liquid​

Answer 1

Answer:

Given the value of coefficient of volume expansion of 5×10

−4

K

−1

As, original density of glycerine

ρ=ρ

0

(1+YΔT)

⇒ρ−ρ

0

=ρ

0

YΔT

Thus, fractional change in the density of glycerin for a rise of 40

0

C in its temperature.
