Textbook Question
Chapter 13, Problem 5RQ
If an object is heated, the temperature of the object will increase. The thermal energy (Q) associated with a change in temperature (ΔT) is a function of the mass of the object (m) and the specific heat (C2). Specific heat is a material property, and values are available in literature. In an experiment, heat is applied to the end of an object, and the temperature change at the other end of the object recorded. An unknown material is tested in the lab, yielding the following results.
- a. Show the resulting data and trendline, with equation and R2 value, on the appropriate graph type (xy scatter, semilog, or log–log) to make the data appear linear.
- b. If the material was titanium, what mass of sample was tested?
- c. If a 4-gram sample was used which of the following materials was tested?

3-55 A multifluid container is connected to a U-tube,
as shown in Fig. P3–55. For the given specific gravities
and fluid column heights, determine the gage pressure at
A. Also determine the height of a mercury column that
would create the same pressure at A. Answers: 0.415 kPa,
0.311 cm
I need help answering parts a and b
Required information
Water initially at 200 kPa and 300°C is contained in a piston-cylinder device fitted with stops. The water is allowed to cool
at constant pressure until it exists as a saturated vapor and the piston rests on the stops. Then the water continues to cool
until the pressure is 100 kPa.
NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part.
Water
200 kPa
300°C
On the T-V diagram, sketch, with respect to the saturation lines, the process curves passing through the initial, intermediate, and final states of the water. Label the
T, P, and V values for end states on the process curves.
