Average human body temperature is 37°C or 310 K what would happen to human life if the melting point of water was above 310 K or if the boiling point of water was below 310 K

This graph shows how the vapor pressure of three liquids varies with temperature: vapor pressure, torr 900 800 700 600 500 400 300 200. 100 0 50 60 70 80 temperature, °C Use the graph to answer the following questions: Which liquid is the most volatile? Which is the least volatile? What is the normal boiling point of each liquid? Note: your answer must be within 1°C of the exact answer to be graded correct. Suppose a beaker of isopropyl acetate is put inside a sealed tank containing isopropyl acetate gas at 80. degree C and 858. torr. After ten minutes, will there be more liquid in the beaker, less liquid, or the same amount? - chloroform isopropyl acetate benzene most volatile: 90 least volatile: chloroform: isopropyl acetate: benzene: more less the same choose one choose one °C °C °℃

Which substance would have the lowest vapor pressure in the liquic state? O CH3CH₂OH 0 H2 O NaCl Ο ΑΙΡΟΔ O CCl4 4

This graph shows how the vapor pressure of three liquids varies with temperature: vapor pressure, torr 900- 800- 700 600- 500- 400 300 200 100- 0+ 100 110 120 130 temperature, °C Use the graph to answer the following questions: Which liquid is the most volatile? Which is the least volatile? What is the normal boiling point of each liquid? Note: your answer must be within 1°C of the exact answer to be Suppose a beaker of pyrrole is put inside a sealed tank containing pyrrole gas at 118. degree C and 512. torr. After ten minutes, will there be more liquid in the beaker, less liquid, or the same amount? — - acetylacetone pyrrole piperidine 140 most volatile: least volatile: acetylacetone: pyrrole: piperidine: more less the same ✓ choose one acetylacetone pyrrole piperidine °C °℃

Note: your answer must be within 1°C of the exact answer to be graded correct. ethylbenzene: piperidine: Suppose a beaker of ethylbenzene is put inside a sealed tank containing ethylbenzene gas at 112. degree C and 237. torr. After ten minutes, will there be more liquid in the beaker, less liquid, or the same more less amount? the same vapor pressure, torr

A student leaving campus for spring break wants to make sure the air in her dorm room has a high water vapor pressure so that her plants are comfortable. The dorm room measures 3.25 m × 4.03 m × 3.04 m and the student places a pan containing 0.580 L of water in the room. Assume that the room is airtight, that there is no water vapor in the air when she closes the door, and that the temperature remains a constant 22 °C. The vapor pressure of water at 22 °C is 19.8 mm Hg. Calculate the pressure that the water vapor would exert if all of the liquid water evaporated. mm Hg Will all of the water in the pan evaporate?

can someone show me the steps for how to solve this problem. I don't know what to do.
