Conversion of water to steam is accompanied by which process?

AAdiabatic
BIsothermal
Correct Answer
CIsochoric
DCyclic

Solution

Conversion from water to steam must be accompanied by rise in volume, so the process is not isochoric. It is not adiabatic as well because the conversion will only take place when heat is added to the system. The process is not cyclic because we are not getting water back. So the process must be isothermal. Infact, all change of states are isothermal processes.
