- 5-81 Compare the number of calories absorbed when 100. g of ice at 0°C is changed to liquid water at 37°C with the number of calories absorbed when 100. g of liquid water is warmed from 0°C to 37°C.arrow_forward5-111 Diving, particularly SCUBA (Self-Contained Underwater Breathing Apparatus) diving, subjects the body to increased pressure. Each 10. m (approximately 33 ft) of water exerts an additional pressure of 1 atm on the body. (a) What is the pressure on the body at a depth of 100. ft? (b) The partial pressure of nitrogen gas in air at 1 atm is 593 mm Hg. Assuming a SCUBA diver breathes compressed air, what is the partial pressure of nitrogen entering the lungs from a breathing tank at a depth of 100. ft? (c) The partial pressure of oxygen gas in the air at 2 atm is 158 mm Hg. What is the partial pressure of oxygen in the air in the lungs at a depth of 100. ft? (d) Why is it absolutely essential to exhale vigorously in a rapid ascent from a depth of 100. ft?arrow_forward5-86 Using the phase diagram of water (Figure 5-20), describe the process by which you can sublime 1 g of ice at-10°C and at 1 atm pressure to water vapor at the same temperature.arrow_forward
- Indicate whether each of the following statements about the physical states of matter is true or false. a. The term indefinite shape applies to both liquids and gases. b. Thermal expansion for a gas is generally less than that of the corresponding liquid. c. The compressibility of a liquid is generally greater than that of the corresponding solid. d. The density of a liquid is about the same as that of the corresponding gas.arrow_forward5-106 The normal boiling point of hexane, C6H14, is 69°C, and that of pentane, C5H12, is 36°C.
