Question

(d) Below 20 K, the specific heat capacity of silver varies with temperature according to the equation
C/Jkg^- 1K^-1 =1.5x10^- 4(T/K)^3 +6.0x10^-3T/K. If a small silver sphere of diameter 4 cm and at 20 K is placed in
25 g of liquid helium at 4 K, what fraction of the liquid will evaporate? Given, density of silver = 1.05 x 10^4 Kgm^-3;
specific latent heat of vaporization of helium = 2.1 x 10^4 Jkg^- 1; boiling point of helium = 4 K.
|(2 + 2 + 2) + (3 + 2) + 5+ 4 = 207​

Answer 1

it is a long question

try googling it

just a tip :)
