Coffee cup calorimeters are considered as an isolated system where no transfer of mass (here water vapor) and no heat loss occurs(also called as adiabatic system ).Since it is given that water vapor are not allowed to escape,so no mass transfer takes place.A coffee cup calorimeter consists of a styrofoam cup which acts as heat insulator( an adiabatic container) ,preventing heat loss to surroundings.The heat released by reaction is wholly transferred to water in which a thermometer is placed which measures initial and final temperature.Specific heat capacity and mass of water(both known ),together with temperatures measured using thermometer can be used to calculate heat released/absorbed.
So,a coffee cup calorimeter (with closed lids to prevent escape of water vapors) is an isolated system
