Unformatted text preview: period of time, the temperature and pressure are found to be uniform throughout the chamber. Find out the final temperature and pressure in the chamber. 4. The voltage drop across an electrical resistor is 10 Volts and the current through it is 1 Ampere. The total heat capacity of the resistor is 20 J/K, and heat is dissipated from the resistor to the surrounding air according to the relation: ( 29 a T T h Q= Where T a is the ambient air temperature, 25 . T is the temperature of the resistor, and h is the heat transfer coefficient which is equal to 0.2 J/Ks. Compute the steady state temperature of the resistor, that is, the temperature of the resistor when the energy loss from the resistor is equal to the electrical energy input....
