The diagram below is just a help.
please help me with that task.

The adjacent circuit with an ohmic resistor and a temperature-dependent resistor is used for temperature detection. Thermistors are conductive materials that have a higher conductivity at high temperatures than at low temperatures. This means that their electrical resistance decreases with increasing temperature.

#1 Calculate the voltage U20 if a temperature of 20 degrees Celsius is measured at the temperature-dependent resistor!

#2 Calculate the temperature of the thermistor with an open circuit voltage U20 = 3.2 V at the temperature-dependent resistor!

thank you.

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

Agas contained within a piston-cylinder assembly e end nation about same energy states, 1 and 2, where pi 10 bar, v undergoes two processes, a and b, between the sam 0.1 m3, ui-400 kj and p2 1 bar, v2 1.0 m2, u2 200 kj: process a: process from 1 to 2 during which the pressure- volume relation is pv constant process b: constant-volume process from state 1 to a pressure of 2 bar, followed by a linear pressure-volume process to +20 0 state 2 kinetic and potential energy effects can be ignored. for each of the processes a and b, (a) sketch the process on p-v coordinates, (b) evaluate the work, in kj, and (c) evaluate process the heat transfer, in kj

To save energy, the air supply to a 2000 ft office has been shut off overnight and the room temperature has dropped to 40°f. in the morning, the thermostat is reset to 70°f and warm air at 120 f begins to flov in at 200ft'/min. the air is well mixed within the room, and an equal mass flow of air at room temperature (changing with time) is withdrawn through a return duct. the air pressure is nearly 1 atm everywhere. ignoring heat transfer with the surroundings and kinetic and potential energy effects, estimate how long it takes for the room temperature to reach 70°f. plot the room temperature as a function of time.
