In a thermonuclear device, the pressure of 0.050 liters of gas within the bomb casing reaches 4.0x10^6 atm. when the bomb causing is destroyed by the explosion the gas is released into the atom sphere where it reaches a pressure of 1.00 atm. what is the volume of the gas after the explosion?

How can a scientist assess whether a pure niobium (nb) sample is responsible for contaminating the lab with radioactivity? test the niobium sample to see whether it now contains other elements.test the niobium sample for the presence of niobium oxide compounds.heat the niobium, and see if the level of radioactivity in the lab increases.place the niobium under pressure, and see if the level of radioactivity in the lab increases.
