Dalton's model of an atom is best described as a. a solar system b. a cloud c. a scoop of chocolate chip ice cream d. a solid sphere

D) A Solid Sphere

Explanation:

As per Dalton's atomic description he said that atom is not divisible and that is the smallest part of atom.

It has no net charge and it can not be divided further. So till Dalton's theory of atom electron and nucleons were not discovered.

So we can consider atom as a model of Solid sphere  because similar to a solid sphere the atom is considered to be unique and not destructible.

So here correct answer will be

D) A Solid Sphere

freezing

deposition

condensation

explanation;

melting also called fusion is the process where solid becomes liquid, sublimation is the process where solid becomes gaseous without first changing to liquid, deposition involves change from gaseous to solid state, freezing involves change from liquid to solid, boiling or evaporation involves change of liquid to gaseous state, while condensation is the change from gaseous state to liquid state.

endothermic reactions involves absorption of heat from the surroundings or the environment while exothermic reactions involves loss of heat energy to the surroundings.

in this case, sublimation, evaporation and melting are endothermic reactions (gain energy from the environment) while, freezing, deposition and condensation are exothermic (loss of energy to the surroundings) reactions.
