1. For liquid-in-glass thermometers, the thermometric property is the change in length of the thermometer liquid with tem- perature. However, other effects are present that can affect the temperature reading of such thermometers. What are some of these?
Reviewing Concepts
2. Answer the following true or false. Explain.
(a) A closed system always contains the same matter; there is no transfer of matter across its boundary.
(b) The volume of a closed system can change.
(c) One nanosecond equals 109 seconds.
(d) When a closed system undergoes a process between two
You are working as a flight-test engineer at the Dryden Flight Research Center. During the low-speed phase of the test program for the X-37, you know that the plane is flying at an altitude of 8 km. The pressure at gage 1 is 1550 N/m2, gage; the pres..
A reversible heat engine operates between 875 K and 310 K and drives a reversible refrigerator operating between 310 K and 225 K. the engine receives 2000 kJ of heat and the net work output from the arrangement equals 350 kJ. make calculations for..
A second-order differential equation x"+9x with initial conditions x(0) = 2 and x'(0) = 0. A first-order differential equation x' + 2x = e^-5t with no initial conditions ( x(0) = x'(0) = 0). Given the differential equation x"+ 6x = f, where f(t) is t..
0.89 pound-mass of water fills a 2.0309 ft^3 weighted piston-cylinder device at a temperature of 400 F. the piston-cylinder device is cooled until its temperature is 90 F. Determine the final pressure of the water and the volume.
77 lbm of a gas whose density is .0007 lbm/ft^3 is mixed with 1.81 lbm of a gas whose density is .0018 lbm/ft^3 such that the pressure and temperature of the gases do not change. Determine the resulting mixtures volume (ft^3) and specific volume (ft^..
At an instant in time during the discharge of a bat- tery, liquid paraffin occupies an annular region of outer radius ro = 19 mm around the battery, which is generating Eg = 1 W of thermal energy. Deter- mine the surface temperature of the battery.
