The half-life for the alpha decay of 24 bk to form am is 1.40x10 y. suppose the energy of the alpha particle is 5.61 mev and that 1.05 g of247bk, freed of any other radioactive materials, were placed in a calorimeter containing 11.9 g of water, initially at 24.5°c. calculate the temperature the water would reach after 1.13 hour. neglect the heat capacity of the calorimeter and heat loss to the surroundings. take the specific heat of water to be 4.184 j k 1 -1 g and the mass of a 24bk atom to be 247.070 u. (1 ev-1.6022 x 109 j) °c
