Question

A vessel is half filled with a liquid at 0 degree centigrade.when the vessel is heated to 100 degree centigrade,the liquid occupies 3/4 volume of the vessel.coefficient of apparent expansion of liquid is
1)0.5/degree C
2)0.05/degree C
3)0.005/degree C
4)0.0005/degree C

Answer 1

Hey dear,

◆ Answer -

K = 5×10^-3 /℃

◆ Explanation -

# Given -

V1 = V/2

V2 = 3V/4

T1 = 0 ℃

T2 = 100 ℃

# Solution -

Coefficient of apparent expansion is the apparent increase in the volume of liquid per unit original volume per degree rise in temperature.

K = (V2-V1) / [V1.(T2-T1)]

K = (3V/4-V/2) / [(V/2)(100-0)]

K = (V/4) / (100V/2)

K = (V×2) / (4×100V)

K = 1/200

K = 5×10^-3 /℃

Therefore, coefficient of apparent expansion is 5×10^-3 /℃.

Thanks dear...
