Science Test 1
| Term | Definition |
|---|---|
| Which type of thermal energy transfer are demonstrated when a wood-burning stove is in use | Conduction, convection, and radiation |
| Conduction is the flow of thermal energy | Through objects that are in direct contact |
| Which type of energy transfer do all objects experience | Radiation |
| A thermal conductor is a material that | transfers thermal energy easily |
| Fleece is considered a thermal insulator because it | does not transfer thermal energy easily |
| imagine grasping on a icy cold handrail with your bare hand on a snowy day. what would likely occur | thermal energy would flow from ur hand into the rail by conduction |
| two objects that are not touching each other may transfer thermal energy by both convection and radiation t/f | true |
| gliders, or sailplanes can fly for many hours by seeking out of rising columns of warm air. the columns of rising air called thermals are an example of convection | true |
| thermal energy always flows from _______ objects to ____ objects | heated, colder |
| which of the following pieces of information cannot be determined from a substance’s phase change graph? assume that the graph shows all states of the substance | the amount of thermal energy required to change the substance’s state |
| which of the following statements correctly defines heat | heat is the movement of thermal energy from an area of higher temperature to an area of lower temperature |
| during a phase change from ice to water, temperature remains constant while added energy is used to | overcome the attractive forces between ice particles |
| vaporization is the phase change from | liquid to gas |
| order the states of matter for any substance from least thermal energy to greatest thermal energy | solid, liquid, and gas |
| the particles in substance A are moving faster then the particles in substance B what must be true abt substance A compared to B | Substance A has higher temp then substance B |
| the law of conservation of energy states that | the total amount of energy in the universe remains constant |
