Now, using the following equation Power= Work (AKA Force X Distance) / Time solve the problems below. 1. How much power does a light bulb contain if it does 600J of work in 5 seconds?
2. How much power does a car have that does 2000J of work in 3 seconds?
3. A machine does 30 J of power in 10 seconds, how much power is that?
4. A race car travels 500 meters with 2000 Newtons of force in 50 seconds. What is the car's power?

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.
