The element radon is at the opposite end of the range, with the lowest specific heat of all naturally occurring elements. Radon'
s specific heat is 94 J/kg°C. If the temperature of a 0.34 kg sample of radon is to be raised by 25°C, how much energy will have to be added to the radon?
In phase would mean both waves are at a positive peak, out of phase would mean one is at a positive whilst the other is at a negative. Out of phase would mean the waves cancel each other out
