Why are nylon ropes used in rock climbing?
a.
nylon ropes are very stiff and therefore shorten the period of time over which a climber's fall is broken.
c.
there is no physical reason for the nylon material, it is just cheaper.
b.
nylon ropes can easily stretch and therefore extends the period of time over which a climber's fall is broken.
d.
none of the above.

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.

i hope that ! =)

like poles repel so keep pushing north to north and repels funny to see this
