Agas changes directly to a solid during(1) fusion (3) saponification(2) deposition (4) decomposition

Answer is: deposition.

Deposition is a thermodynamic process in which gas transforms into solid without passing through the liquid phase.  

For example, forming snow in clouds directly from water vapor.

During deposition phase change, energy is released.  

Another example, the phase change H₂(g) → H₂(s) is called deposition and the enthalpy change, ΔH, for this phase change has a negative (-) sign.  

answer: option (4) is the correct answer.

explanation:

areas which are at low altitudes and near the equator tend to receive direct sunlight from the sun. hence, heat energy or radiations from the sun make these areas warmer and they have warmest water.

whereas areas which are at high altitudes and away from the equator do no receive direct sunlight. hence, no direct contact from the sun makes these regions colder and thus, they have colder water.

thus, we can conclude that the statement areas at low latitudes near the equator have the warmest water because they receive the most direct sunlight best explains the relationship between an area's geography and the temperature of its surface water.
