Astatine is an extremely rare element with an estimated 28 g total on Earth. How much energy would be required to heat Earth's entire supply of astatine by 10.0 °C assuming it has a specific heat capacity similar to iodine, 0.214 J g^-1 °C^-1?

Question

Quizplus · Accepted Answer

The energy required can be calculated using the formula q = mcΔT. With m = 28 g, c = 0.214 J/g°C, and ΔT = 10.0 °C, the energy q = 28 * 0.214 * 10 = 59.92 J, which rounds to 60 J.
