Temperature | ||
#1 | The transfer of energy moves from an object with? temperature to and object with? temperature | High to low |
#2 | Name the three scales used on a thermometer | Celsius, Farenheit and Kelving |
#3 | What is the temperature when all molecular motion stops? | Absolute zero |
#4 | If the particles of an object have high average kinetic energy, is the temperature high or low? | Hight |
#5 | Who invented the thermometer | Galileo |
Heat Transfer | ||
#1 | What happens when an object at a hight temperature touches an object at a lower temperature | Heat energy moves from higher to lower temperatures |
#2 | When both objects reach the same temperature this is called | Equalibrium |
#3 | How is heat transferred in a pan on a stove burner. | Conduction |
#4 | How is heat transferred through a solid. | By one particle at a time |
#5 | What type of material slows down the movement of heat energy? | Insulators |
Convection and Radiation | ||
#1 | How is heat transferred in liquids and gases? | Convection |
#2 | In the convection tubes, the hot water is more or less dense than the cold water? | Less dense |
#3 | The transfer of thermal energy by electromagnetic waves is called? | Radiation |
#4 | Which type of thermal energy transfer does not need particles of matter to move heat? | Radiation |
#5 | Identify the type of heat transfer-Roasting a hot dog over a campfire (Lightis invovled) | Radiation |
Examples of Heat Transfer | ||
#1 | Identify the type of heat transfer-Heating pad you are sitting on | Conduction |
#2 | Hot air circulating in a room via the furnace | convection |
#3 | How does your coat keep you warm? | Traps air between you and the coat. |
#4 | Is a sytrofoam cup an insulator or a conductor? | Insulator |
#5 | Is copper tubing(metal pipe) an insulator or a conductor? | Conductor |
Thermal Energy | ||
#1 | When an object is heated, what happens to the molecules of that object? | Speed up |
#2 | If an object is heated does the particles expand or do the space between the particles expands? | Space between the particles |
#3 | Why do bridges and roads have expansion joints? | To allow for thermal expansion |
#4 | When this object was heated, what happened? And what was this called? | It is expanded, Thermal Expansion |
#5 | Which has more thermal energy-an iceberg or the cup of coffee? Why? | Ice berg-more particles |
Final Question | |
What is the Greenhouse effect? | The warming of the Earth-due to the trapping of infrared heat. |
