1) While diving in Cancun, Mexico, where the seawater has a density of 1,015 kg/m³, Nana observed that her pressure meter device reading was 3.75 atm. The reading at sea level is the standard 1.0 atm. At what depth is she diving when the meter read 3.75atm? 2) a) What is the rms-speed V of the Oxygen molecules at rms 25 degrees Celsius? 32g/mol, MN2 28g/mol %3D |3D b) Calculate the average speed V for Oxygen at 25 avg degrees Celsius. c) What is the average translational KE of Oxygen molecule at 293 K? 3A) One (1) mole of an ideal gas receives an input of 630J of energy in the form of heat. The gas does 325J of work on its surroundings by expanding. a) Find the change in its internal energy. b) Using your answer from part a) calculate the temperature change AT.

Humans evolved in Earth's atmosphere, therefore the pressures interior to the body are relatively close to atmospheric pressure. Because the differences between internal body pressures and atmospheric pressure are so small, individuals have a difficult time gauging the magnitude of atmospheric pressure. Suppose an individual is lying on his stomach with sheets of paper stacked on his back. If each sheet of paper has a mass of 0.00280 kg and is the standard letter size of 8.5 in by 11 in (0.216 m by 0.279 m), how many sheets must be stacked to produce a pressure on his back equal to atmospheric pressure (roughly 101325 Pa)?
