1.	Canthe givenheatenergybecompletely converted to workin a cyclicprocess? Ifnot ,whencan theheat cancompletelyconvertedto work ?
Answer» Solution :ACCORDING to first law of thermodynamics WORK can be completely converted into heat. Since the SYSTEM COMES back to the initial stage, the CHANGE in the internal energy is zero. In cyclic process, heat can flow in to system and heat flow out of the system. The net heat transferred to the system is equal to work done by the gas. `Q_("net") = Q_("in") -Q_("out")= W"(for a cyclic process)"`
