The element radon is at the opposite end of the range with the lowest specific heat of all
naturally occurring elements. At 25°C, radon's specific heat is 94 J/kg°C. If the temperature
of a 0.34 kg sample of radon is to be raised from 0°C to 50°C, how much energy will have
to be added to the radon? Show work.
