A. Atoms gain energy during evaporation and boiling.
Explicação
## Step 1<br />Evaporation and boiling are both processes where a substance changes from a liquid state to a gas state. This process requires energy, which is known as the latent heat of vaporization.<br /><br />## Step 2<br />During evaporation, the molecules of the substance absorb energy from their surroundings. This energy is used to break the intermolecular forces that hold the molecules together in the liquid state, allowing them to escape into the gas phase.<br /><br />## Step 3<br />Similarly, during boiling, the molecules of the substance also absorb energy from their surroundings. This energy is used to break the intermolecular forces that hold the molecules together in the liquid state, allowing them to escape into the gas phase.<br /><br />## Step 4<br />Therefore, in both evaporation and boiling, atoms gain energy. This is because the energy absorbed is used to break the intermolecular forces holding the atoms together in the liquid state, allowing them to escape into the gas phase.
