Under which conditions will the volume of a gas be greatest? O T= 273K and P = 0.25 atm
O T= 273K and P = 2 atm
T= 300K and P = 0.25 atm
O T= 300K and P = 2 atm

Americium-241 undergoes fission to produce three neutrons per fission event. if a neutron-absorbing material is mixed in with this sample so that the rate of neutron production drops down to 1.8 neutrons per fission event, which will be effective at achieving a critical mass? check all that apply. remove a deflective shield surrounding the sample. remove absorbent material mixed in with the sample. compress the sample of americium-241.
