| Question | Answer |
|---|---|
| A material that reduces the flow of heat by conduction, convection, and radiation | insulator |
| what are good conductors of heat | metal |
| the transfer of energy that does NOT require matter is | radiation |
| energy travels from the sun to earth as | radiant energy |
| the inside surface of the glass inside a vaccum bottle is coated with alluminum to prevent heat loss by | radiation |
| large tank for storing water heated by the sun and pumps to move water | forced air |
| the sum of the kinetic and potiental energy of all the particles in an object are | thermal energy |
| the average kinetic energy of the particles in an object | temprature |
| the transfer of thermal energy in a fluid by the movement from place to place | convection |
| the transfer of thermal energy by cloisions between particles | conduction |
| the transfer of energy by electromagnetic waves | radiation |
| a material in which heat flows slowly | insulator |
| active solar heating systems use this | solar collectors |
| thermal energy,heat,and work are related, and the study of the relationship between them is... | thermodynamics |
| the increase in thermal energy of a system equals the work done on the system equals the work done on the system plus the heat transfered to the system | first law of thermodynamics |
| that its possible for heat to flow from a cool object to a warmer object unless work is done | second law of thermodynamics |
| a device that converts heat into work | heat engine |
| the heat engine in a car | internal combustion engine |
| thermal energy that flows from something at a higher temprature to something at a lower temprature | heat |
| the amount of heat that is needed to raise the temprature | specific heat |
