O GASES Solving applications of Boyle's Law Omar V A marine biologist is preparing a deep-sea submersible for a dive. The sub stores breathing air under high pressure in a spherical air tank that measures 87.0 cm wide. The biologist estimates she will need 7100. L. of air for the dive. Calculate the pressure to which this volume of air must be compressed in order to fit into the air tank. Write your answer in atmospheres. Round your answer to...

O GASES Using the ideal equation of state Thomas v A chemical engineer must calculate the maximum safe operating temperature of a high-pressure gas reaction vessel. The vessel is a stanless steel cylinder that measures 48.0 cm wide and 57.6 cm high. The maximum safe pressure inside the vessel has been measured to be 5.00 MPa For a certain reaction the vessel may contain up to 3.83 kg of dinitrogen monoxide gas. Calculate the maxmum safe operating temperature the engineer...

III O GASES Using the ideal equation of state Gabrielle v A chemical engineer must calculate the maximum safe operating temperature of a high-pressure gas reaction vessel. The vessel is a stainless-steel cylinder that measures 29.0 cm wide and 34.8 cm high. The maximum safe pressure inside the vessel has been measured to be 6.90 MPa. For a certain reaction the vessel may contain up to 0.815 kg of carbon monoxide gas. Calculate the maximum safe operating temperature the engineer...

When gas expands in a cylinder with radius r, the pressure P at any given time is a function of the volume V: P = P(V). The force exerted by the gas on the piston (see the figure) is the product of the pressure and the area: F = ner2p. The work done by the gas when the volume expands...

Practice | MCAT P QUESTION If the air wedge is filled with water, how are the wavelength and the distance between dark bands affected? (Select all that apply.) The wavelength decreases. O The wavelength increases. The interference bands get farther apart. O The interference bands get closer together Recall how the wavelength is affected by the index of refraction of the medium. See equation below and the surrounding material for help. Does a shorter wavelength make...

Find P air and V air ..
Water vapor accounts for part of the gas volume and S8 lle volum u sued must be corrected for the water vapor present. The vapor pressure of the water depends on temperature and the vapor pressure of water (PH,o) at different temperatures can be found in Table 1. If a Ph,o value at a particular temperature is not usted in the table, then it has to be found through the interpolation method from...

At -17.0°C the pressure equilibrium constant k, =3.9% 10-for a certain reaction. Here are some facts about the reaction: • The net change in moles of gases is -1. • Some of the reactants are liquids and solids. al • If the reaction is run at constant pressure, 148. kJ/mol of heat are released. Yes Using these facts, can you calculate K, at -35. °C? No. х $ ? If you said yes, then enter your answer at right. Round...
