Which best compares freezing and condensation? both involve changes between liquids and gases. both involve changes between gases and solids. both involve the release of heat. both involve the absorption of heat.

Both involve the release of heat

If you think about it, this makes sense intuitively because the change in state (liquid to solid/ gas to liquid) involves going from a state of matter where the atoms are moving quickly to a state where it is moving slower. The change in this movement is released as energy (heat).

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.

Ibelieve the answer is d. macula  hope my answer has you : )
