A chemistry graduate student is designing a pressure vessel for an experiment. The vessel will contain gases at pressures up to 70.0 MPa. The student's design calls for an observation port on the side of the vessel (picture). The bolts that hold the cover of this port onto the vessel can safely withstand a force of 2.40 MN. Calculate the maximum safe diameter w of the port. Round your answer to the nearest 0.1cm

- Part B The kinetic molecular model details other aspects of gas particle motion and collisions besides speed. Open the Run Experiment tool under the Experiment tab in the simulation, and then select the Submicroscopic tab. You can track the motion of an individual gas particle by clicking the Track button in the lower right corner, and you can track a different gas particles by first clicking Pause, then clicking on a gas particle, and finally clicking Resume Change several of the macroscopic conditions (temperature, pressure, and volume) of th over a consistent amount of time (e.g, 10 s). Then, complete the following statements that describe the atomic behavior of a gas particle. ideal gas and observe how the movement of a tracked gas particle is affected by those changes and collisions. For each condition, make your observations Match the words in the left column to the appropriate blanks in the sentences on the right. Make certain each sentence is complete before submitting your…

Assuming the initial gas pressure are equal, match the gas to the appropriate cylinder in the diagram. The three gases you can chose from are Cl₂, N₂, and CO₂. blue: CO2 red: N2 green: C12

Please do all parts if possible, I dont need explanation just answer, Thank you:   TRUE OR FALSE:  a) Glasses are usually harder than plastics but softer than silicon carbide and boron carbide b)  Any amorphous (lacking in long-range periodic order) materials, inorganic, organic, or metallic, formed by any techniques, exhibits glass transformation formation behavior are glasses  c) In general, the viscosity is low at the melting position of glass, and high at room temperature. d) In general, if the viscosity is very high at the melting position of the corresponding crystalline phase which would form the melt, it is much easier to form glass for this melt. e) The glass fiber is possible to have a tensile strength even larger than that for iron or structural steel. Therefore, in the practical applications, we should be able to use glasses for the same purposes of the iron or structural steel.
