Based on the model of interaction between spherically symmetric expanding matter and the
external medium, we have estimated the parameters of the matter heated by the shock that was produced
in the envelope ejected by the explosion of a classical nova during its interaction with the stellar wind from
the optical companion. Using this model, we have shown that the matter ejected during the outburst in the
system CI Camelopardalis had no steep velocity gradients and that the reverse shock could heat the ejected
matter only to a temperature of ∼0.1 keV. Therefore, this matter did not contribute to the mean temperature
and luminosity of the system observed in the energy range 3–20 keV.
