5g of hydrogen gas at initial pressure 3 atm and an initial temperature 27℃ are compressed adiabatically to one half the initial volume. If the specific heat capacities for hydrogen gas are = 1.03 × 104/. and = 1.44 × 104/. . Determine i. The final pressure (4) ii. The final temperature (2) iii. The work done by the gas (2

Truck traveling west on the highway experiences an acceleration to the east. what could be the cause of this acceleration

Consider a hydrogen atom in the ground state. what is the energy of its electron? =e= jj now consider an excited‑state hydrogen atom. what is the energy of the electron in the =5n=5 level? =e5= j

Adiver named jacques observes a bubble of air rising from the bottom of a lake (where the absolute pressure is 3.50 atm) to the surface (where the pressure is 1.00 atm). the temperature at the bottom is 4.00 ∘c, and the temperature at the surface is 23.0 ∘c.what is the ratio of the volume of the bubble as it reaches the surface (vs) to its volume at the bottom (vb)? if jaques were to hold his breath the air in his lungs would be kept at a constant temperature. would it be safe for jacques to hold his breath while ascending from the bottom of the lake to the surface?
