Concept explainers
(a)
Interpretation:
The given statement “for systems in a state of physical equilibrium, no net macroscopic changes can be detected” is true or false has to be indicated.
Concept Introduction:
Physical equilibrium is a state in which two physical processes which are opposing to each other takes place at the same rate at this moment there is no net macroscopic changes can be happened but system is dynamic and at equal rate the forward and reverse process are occurred.
(b)
Interpretation:
The given statement “for a liquid-vapor equilibrium situation, the two opposite processes occurring are evaporation and condensation” is true or false has to be indicated.

- A special vessel (see Fig. 10.45) contains ice and supercooled water (both at 10C) connected by vapor space. Describe what happens to the amounts of ice and water as time passes.arrow_forwardElemental carbon has one gas phase, one liquid phase, and two different solid phases, as shown in the phase diagram: (a) On the phase diagram, label the gas and liquid regions. (b) Graphite is the most stable phase of carbon at normal conditions. On the phase diagram, label the graphite phase. (c) If graphite at normal conditions is heated to 2500 K while the pressure is increased to 1010 Pa, it is converted into diamond. Label the diamond phase. (d) Circle each triple point on the phase diagram. (e) In what phase does carbon exist at 5000 K and 108 Pa? (f) If the temperature of a sample of carbon increases from 3000 K to 5000 K at a constant pressure of 106 Pa, which phase transition occurs, if any?arrow_forwardExplain why evaporation leads to cooling of the liquid.arrow_forward
- Why do liquids have a vapor pressure? Do all liquids have vapor pressures? Explain. Do solids exhibit vapor pressure? Explain. How does vapor pressure change with changing temperature? Explain.arrow_forwardIndicate whether each of the following statements concerning boiling and boiling point is true or false. a. A liquid can be made to boil at temperatures higher than its normal boiling point. b. A liquid can be made to boil at temperatures lower than its normal boiling point. c. In a boiling liquid, vapor formation occurs within the body of the liquid. d. To compare the boiling points of two different liquids, the external pressure should be the same.arrow_forward
