Question
3. PuO2 has a density of 11.5 g cm- and a specific heat capacity of 330 J kg' K-1. A particular old sample
(i.e. one that has 'partially decayed*) of PuO2 produces 0.440 kW kg' of heat due to internal radioactive
decay.
> The power output of a 2.00 cm' sample of this partially decayed' PuO2 is therefore 10.2 J/s.
PuO, melts at 2673 K and its latent heat of fusion is 245 kJ kg:!.
If we place our 2.00 cm block in a well insulated and heat resistant container when it is at 300 K, then how
long is it before the whole block is melted?
