G Part 2: The features arrived the grammar Splitting categories and non-terminals gets out of hand fast. An alternative to the proliferation of non-terminals is to attach features to the terminals and non-terminals, and use these features to constrain the grammar. Consider the case example in part 1. We split pro into pro_nom and pro_acc, and we split np into np_nom and np_acc. The sequence det n could be either, so we added two rules (one for np_nom, and one for np_acc) with identical right-hand sides. Instead of splitting the symbols of the grammar, we can modify the lexical entries as follows:

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.
