Why does a space shuttle turn to the east as rapidly
aspossible after launch? consider the earth's rotation on
itsaxis.

To boost its acceleration because the Earth rotates Eastwards and to ensure that any crash will occur on an ocean and huge loss in life and properties will be averted.

Explanation: A space shuttle turns to the east as soon as possible,this is to ensure that the space shuttle acceleration is supported by Earth rotation which is also Eastwards.

Another reason for ensuring that the space shuttle turns Eastwards as soon as possible is to prevent a huge loss of life if there is any chance of crash by the space shuttle.When the space shuttle turns Eastwards it will ensure that any crashing will possibly be on the an ocean hence a huge loss of life an property in populated areas will be averted or reduced.

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.
