No nuclear reactions occur in the interior of a white dwarf. its brilliance comes from stored heat. therefore, the fate of an isolated white dwarf is to slowly lose its stored energy and dim over a long period of time. however, if a white dwarf is a member of a binary-star system with specific properties, the white dwarf can become explosively active. label the components of such a binary-star system capable of producing a nova event.
a. mass-transfer stream
b. accretion disk
c. main-sequence or giant companion star
d. white dwarf

Arigid tank is divided into two equal parts by a partition. one part of the tank contains 3 kg of compressed liquid water at 400 kpa and 60°c while the other part is evacuated. the partition is now removed, and the water expands to fill the entire tank. determine the entropy change of water during this process, if the final pressure in the tank is 40 kpa. use steam tables.
