Mia and claire are 3-year-olds at free play in their preschool. mia has a lacy apron tied around her head like a wedding veil, and claire has a sheer curtain tied over her shoulders like a cape. each is holding a wandone is a stick with a star on the end, and the other is a long tinker toy stick with one wheel connector at the end. when asked what they're doing, mia says, we're playing fairy. we're both fairies. what kind of play are they engaging in

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.
