Answer :
Final answer:
The energy required to raise the temperature of a 0.34 kg sample of radon by 25°C is 799.5 J.
Explanation:
The specific heat of a substance determines the amount of energy required to raise its temperature by a certain amount. In this case, we are given the mass of radon (0.34 kg), its specific heat (94 J/kg°C), and the change in temperature (25°C). To calculate the energy required, we can use the formula:
Energy = mass × specific heat × change in temperature
Plugging in the values, we have:
Energy = 0.34 kg × 94 J/kg°C × 25°C = 799.5 J
Therefore, the amount of energy that needs to be added to the radon sample is 799.5 joules.
