A one-gram sample of thorium 228 90 Th contains 2.64 3
Chapter , Problem 65(choose chapter or problem)
A one-gram sample of thorium 228 90 Th contains 2.64 3 1021 atoms and undergoes a decay with a half-life of 1.913 yr (1.677 3 104 h). Each disintegration releases an energy of 5.52 MeV (8.83 3 10213 J). Assume that all of the energy is used to heat a 3.8-kg sample of water. Concepts: (i) How much heat Q is needed to raise the temperature of a mass m of water by DT degrees? (ii) The energy released by each disintegration is E. What is the total energy Etotal released by a number n of disintegrations? (iii) What is the number n of disintegrations that occur during a time t? Calculations: Find the change in temperature of the 3.8-kg sample of water that occurs in one hour.
