A solid substance has been given a specific amount of energy to directly change its phase to gas state. This process is termed as:

Option 1 -> Evaporation is the phase transition from liquid to gas, not solid to gas.

Option 2 -> Transpiration is a biological process where plants release water vapor, not a phase change process.

Option 3 -> Condensation is the reverse process where gas changes to liquid state.

Option 4 -> Sublimation is the direct phase transition from solid to gas without passing through the liquid phase.

Hence, Option 4: Sublimation -> When a solid substance is given sufficient energy to directly transition into gaseous state, bypassing the liquid phase entirely, this is called sublimation. Common examples include dry ice (solid CO₂) and naphthalene balls -> correct
