** Abstract: **
In has been shown that the heat capacity (C_{p}), coefficients of heat
conductivity, (\lambda) and thermal expansion, (\alpha), for the
amorphous selenium are dependent on the temperature of the transition from
glass-forming state into a high elasticity condition. On this transition
these quantities are increased by AC_{p}=3,47 kal/deg\cdotmol, \Delta\
\lambda=0,32\cdot 10^{-3} cal/sec\cdot deg., \delta\alpha=0,79\cdot
10^{-5} deg^{-1}.
These increments are due to the contribution by the increased concentration
of holes. Contribution of holes in the glass-forming region was calculated
using the formulae by Hirai and Eyring for 1 mol of \lq\lq heads", which is
equal to C_{p}=3,06 kal/deg\cdotmol.
The \lq\lq hole" theory for liquids is used as a strating point in the
calculation of the \lambda and \alpha. The obtained resuls are: \lambda
=0,28\cdot 10^{-3} kal/cm\cdotsec\cdotdeg. \alpha=0,73\cdot 10^{-5}
deg^{-1}. These quantities for C_{p}, \lambda and \alpha are in
satisfactory agreement with experimental data.
