calculate the moles of hydrogen and the pressure in each flask where the volume is negligible. Each flask is originally 275K with .455 mols of hydrogen gas and .7atm of pressure. Then one flask is heated to 500K while the other remains at 275K
The diameter of the pressure vessel is 450 mm and its length is 2.0 m. Determine the maximum internal pressure that can be applied if the longitudinal stress is limited to 140 MPa, and the circumferential stress is limited to 60 MPa
What benefits does one provide over the other and what pitfalls must the professional be aware of?
Radio astronomers often study the radiation emitted by a hydrogen atom from a transition between the two hyperfine levels associated with the ground state

A water tank, 22 ft in diameter, is made from steel plates that are ½ in. thick. Find the maximum height to which the tank may be filled if the circumferential stress is limited to 6000 psi. The specific weight of water is 62.4 lb/ft.
The strength of longitudinal joint in Fig. 1-17 is 33 kips/ft, whereas for the girth is 16 kips/ft. Calculate the maximum diameter of the cylinder tank if the internal pressure is 150 psi.
In a first order decomposition in which the rate constant is 0.201 sec-1, how long will it take (in seconds) until 0.131 mol/L of the compound is left, if there was 0.566 mol/L at the start
