(Solved): Write and simplify the general energy balance for each of the following processes. Begin by definin ...



Write and simplify the general energy balance for each of the following processes. Begin by defining the system as closed or open, then writing the appropriate form of the general energy balance. Cancel out negligible terms and indicate what keyword/assumptions allows the term to be assumed negligible. State whether heat and work terms are positive or negative or zero. a. The contents of an agitated, sealed flask are heated from

25\deg C

to

80\deg C

.. b. An exothermic chemical reaction takes place in a closed, perfectly insulated, rigid container. c. Repeat part (b), only suppose that the reactor is isothermal rather than perfectly insulated. d. Water is pumped from the bottom of a well

20m

below the ground through a

2-cm

ID pipe, through the water heater and to your shower

1m

above the ground. The shower head has a cross-sectional area of

1cm^(2)
