Textbook Question
Chapter 18, Problem 4P
In Chapter 12, we explained that the electric power consumption of various electrical components can be determined using the following power formula: P = VI = RI2 where P is power in watts, V is the voltage, I is the current in amps, and R is the resistance of the component in ohms.
Plot the power consumption of an electrical component with a resistance of 145 ohms. Vary the value of the current from zero to 4 amps. Discuss and plot the change in power consumption as the function of current drawn through the component.

3-1 The molecular weight of carbon dioxide, CO2, is 44. In an experiment the value y for
CO2 was found to be 1.3. Assuming that CO2 is a perfect gas, calculate the gas
constant, R, and the specific heats at constant pressure and constant volume, Cp, Cv
(0.189 kJ/kg.K; 0.63kJ/kg.K; 0.819kJ/kg.K)
3-2 Oxygen, O2, at 200 bar is to be stored in a steel vessel at 20°C the capacity of the vessel
is 0.04m³. Assuming that O₂ is a perfect gas, calculate the mass of oxygen that can be
stored in the vessel. The vessel is protected against excessive pressure by a fusible plug
which will melt if the temperature rises too high. At what temperature must the plug
melt to limit the pressure in the vessel to 240bar? The molecular weight of oxygen is 32
(10.5 kg; 78.6°C)
3-3 A quantity of a certain perfect gas is compressed from an initial state of 0.085m³, 1 bar
