A hamster running on a wheel generated 180 J of work, but the hamster's power was only 10 W. How long did it take for the hamster to generate that much work?

18s

Explanation:

Given parameters:

Work done by hamster = 180J

Power of hamster  = 10W

Uknown:

Time taken for the hamster to generate the work  = ?

Solution:

Power can be defined as the rate at which work is being done by a body. It is related to both work done and time by the expression below;

         Power  =

    Time taken  =

     Time taken  =    = 18s

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.
