You are given a black box with three terminals, as shown below. the box is known to
contain five 1-ohm resistors.
a
b
c
using an ohm-meter, you measure the resistance between the terminals to be the following:
a - b: 1.5 ohms
b - c: 3 ohms
a - c: 2.5 ohms
determine the configuration of the five resistors inside the box.

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.

An air conditioning system consist of a 5 cm diameter pipe, operating at a pressure of 200 kpa. the air initially enters the pipe at 15°c with a velocity of 20 m/s and relative humidity of 80%. if the heat supply throughout the process is 960 w, determine the relative humidity and the temperature at the outlet
