Question

what process best describes when a solid gains energy and becomes a gas? sublimation condensation vaporization

Explanation:

• Sublimation is the process where a solid directly turns into a gas without passing through the liquid state, which matches the description of a solid gaining energy and becoming a gas.
• Condensation is the process of a gas turning into a liquid, so it's incorrect.
• Vaporization is the process of a liquid turning into a gas, so it's also incorrect.
