Part A. Estimate the decay rate of a liter of water in decays per second. Express your answer using two significant figures.
Part B. Estimate the decay rate of a liter of water in curies.Part C. How does this compare to a small (by laboratory standards) radioactive source of one microcurie?
The volume of a monatomic ideal gas increases by a factor of 4 in an adiabatic expansion. Calculate By what factor does its pressure change
