The half-life for the alpha decay of24 bk to form24am is 1.40x10 y. suppose the energy of the alpha particle is 5.61 mev and that 1.05 g ofbk, 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 g and the mass of a bk atom to be 247.070 u. (1 ev 1.6022 x 1019 j) °c
