- Q22. The archer above shoots an arrow toward a target. Which object has the GREATEST kinetic energy?archerbowtargetarrow30s
- Q3Unlike potential energy, kinetic energy—remains constant as an object moves fasterIncreases as an object moves fasterdecreases as an object moves fastercannot exist as an object move faster30s
- Q4Toasters are small appliances used to cook bread until it is darker and crisper. Which type of energy transformation happens in a toaster?Chemical to radiantElectrical to thermalChemical to electricalChemical to thermal30s
- Q5Which type of heat transfer is happening when the sun warms your face?convectionconductionplasmaradiation30s
- Q6Complete the statement. When a battery is used to light the flashlight, the energy transformations that occur are chemical energy → electrical energy →____? _______radiant energykinetic energymechanical energymotion energy30s
- Q7Finn has a toy airplane he likes to play with after school. The airplane has a plastic propeller connected to a rubber band. Turning the propeller several times stores energy in the rubber band. When Finn lets it go, the propeller spins and the toy airplane flies through the air. Which statement below best describes the type of energy transformation that makes the plane fly?potential energy to kinetic energykinetic energy to potential energymechanical energy to electrical energyelectrical energy to mechanical energy30s
- Q8The lantern in the diagram uses kerosene, a petroleum-based fuel. Use the illustration of the kerosene lantern to answer the question. Which type of energy conversion is happening in the lantern to produce light?chemical to nuclearchemical to radiantradiant to chemicalradiant to mechanial30s
- Q9The picture below shows eggs being cooked in a pan on the electrical stove. What kind of energy transformation is occurring on the stove?mechanical energy is changed to chemical energyradiant energy is changed to thermal energythermal energy is change to electrical energyelectrical energy to changed to thermal energy30s
- Q10Emilie holds the end of a metal rod in the flame of a Bunsen burner. After a couple of minutes the rod becomes too hot for Emilie to hold. Which of the following caused the heating of the rod?convectionconductioninductioninsulation30s
- Q11Which of the following is an example of conduction?hot air drying a wet towelheat rising from the coils of a stovesolar energy warming a roomHeat moving from a clothes iron to a shirt30s
- Q12A student observes a teacher conducting a demonstration using a hot plate and beaker of water. What transformation of energy causes the water to increase in temperature?electrical energy to radiant energythermal energy to radiant energyradiant energy to thermal energyelectrical energy to thermal energy30s
- Q13Which of the following is an example of heat transfer through radiation?a pot of soup warming on a hot burneran egg getting cooked in a pot of boiling watera crayon melting on a hot sidewalkbeach sand getting warmed by the Sun30s
- Q14When an egg is boiled in a pot of water on the stove, there is more than one kind of heat transfer. Heat is transferred from the stove to the pot directly since they are physically touching. Heat is also transferred from the pot to the egg, carried through the water. What two kinds of heat transfer are represented?Stove to Pot = conduction, Water to Egg =radiationStove to Pot = conduction, Water to Egg =radiationStove to Pot = radiation, Water to Egg =conductionStove to Pot = conduction, Water to Egg=convection30s
- Q15During which process does heat transfer occur because of density differences?radiationreflectionconductionconvection30s
