Hold a 50 g sphere of copper in one hand and a 25 g sphere of aluminum in the other hand. if both absorb energy at the same rate, which will come to your body temperature first and why? the specific heat capacities are 0.4 j/(g ⋅ ) for copper and 0.9 j/(g ⋅ ) for aluminum.

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.
