• ray creates an energy transfer diagram for a hair dryer. however, the diagram contains an error that could be corrected in several different ways. an illustration of a very wide arrow with a hair dryer at the tail labeled electrical energy 750 j. the arrow breaks into a 3 arrows a medium arrow going straight labeled kinetic energy 125 j and a much larger arrow curling away labeled thermal energy 550 j and the smallest curling away labeled sound energy 150 j. which of these changes would make the diagram error-free? check all that apply. reducing the amount of thermal energy to 475 j increasing the amount of electrical energy to 825 j increasing the amount of sound energy to 225 j reducing the amount of kinetic energy to 50 j reducing the amount of electrical energy to 675 j

• an uncovered pot of water lies out in the sun. which statements correctly describe what happens at the surface of the liquid water? the vapor pressure remains constant regardless of the water temperature. the vapor pressure is produced by water molecules that have evaporated. the vapor pressure increases as the sun heats the water in the pot. evaporation stops once the vapor pressure reaches a certain point. evaporation and condensation both occur on the liquid’s surface.
