3.87 WP As shown in Fig. P3.87, a well-insulated tank fitted with an electrical resistor of negligible mass holds 2 kg of nitrogen (N₂), initially at 300 K, I bar. Over a period of 10 minutes, electricity is provided to the resistor at a constant voltage of 120 volts and with a constant current of 1 ampere. Assuming ideal gas behavior, determine the nitrogen's final temperature, in K, and the final pressure, in bar.

3.87 WP As shown in Fig. P3.87, a well-insulated tank fitted with
an electrical resistor of negligible mass holds 2 kg of nitrogen (N₂),
initially at 300 K, 1 bar. Over a period of 10 minutes, electricity is
provided to the resistor at a constant voltage of 120 volts and with a
constant current of 1 ampere. Assuming ideal gas behavior, determine
the nitrogen's final temperature, in K, and the final pressure, in bar.
