4 Sc Ch 12 Heat
| Question | Answer |
|---|---|
| the transfer of passing energy | conduction |
| a material that allows thermal energy or electricity to pass through it | conductor |
| the pattern in which thermal energy flows; formed when heated liquid or gas expands and is less dense than a cooler liquid or gas around it | convection current |
| a material or substance that limits the amount of heat that passes through it | insulator |
| the transmission of energy as light | radiation |
| total energy of motion of particles in a system | thermal energy |
| describe the arrangement of particles of a solid | they are all closely packed together |
| describe the speed of the particles of an object that is warm/hot | the particles are moving fast |
| describe the speed of the particles of an object that is cool/cold | the particles are moving slow |
| When a substance cools, it (expands or contracts) | contracts |
| when a substance heats up, it (expands or contracts) | expands |
| Wheat is temperature? | it is the measure of the AVERAGE AMOUNT of motion of particles in matter |
| Which type of heat transfer is being done when a pot is on a hot stove burner (conduction, radiation or convection)? | conduction |
| What are insulators? | a material or substance that limits the amount of heat that passes through it |
| As hot air expands and cool air sinks below the warmer air, what is formed? | convection current |
| the heat given off from a heat source through electromagnetic waves (like a campfire or light bulb) is what type of heat transfer? (conduction, radiation or convection) | radiation |
| Thermal energy measures the total energy of moving ____. | particles |
| Which method of heat energy transfer that does not require matter? (conduction, radiation, or convection) | radiation |
| what type of heat transfer causes a mobile to turn? (conduction, radiation or convection) | convection |
| what is energy? | ability to do work or cause a change |
| how is an insulator different from a conductor? | an insulator only lets in a little heat. A conductor lets in a lot. |
| If your bedroom has a radiator heater, explain how the room gets warmer. | Water is heated in a boiler. Then the hot water or steam is pumped into pipes throughout the room and the convection current heats up the room |
| Name some example of Convection current: (3) | radar and air, wind, oven |
| Name an example of Conductor: (1) | touching a light bulb |
| Name some examples of Radiation: (3) | sun, fire, light bulb |
| Name some examples of Insulators: (5) | marble, wood, air, cardboard, plastic |
| energy due to moving particles that make up matter | thermal energy |
| the transfer of heat energy by one thing touching another | conduction |
| material that readily allows heat to move | conductor |
| material that limits the amount of heat that passes through it | insulator |
| pattern of flowing heat energy | convection current |
| heat energy that travels through space from a light source such as the sun | radiation |
| What is the effect of: boiler heats up water | it turns to steam |
| What is the effect of: radiators made of metal | allows heat energy from the steam to pass through the walls of the radiator |
| What is the effect of: air is heated & expands | it is less dense than the cooler air around it |
| What is the effect of: warm air is less dense than cooler air | the cooler air sinks below the warmer air |
| Heat is the flow of thermal energy (true or false) | true |
| (Temperature or Thermal Energy)is the total energy in all of the particles in an object | thermal energy |
| Liquids expand when they are heated and (expand or contract) when they are cooled? | contract |
| temperature is measured using a (thermometer or scales) | thermometer |
| the number of particles in an object affects its thermal energy by not its temperature (true or false) | true |
| a large pot of water and a small pot of water with the same temperature have the (same or different) thermal energy? | different - the large pot has more thermal energy |
| An object with a high temperature has particles that move (quickly or slowly) | quickly |
| wood & plastics are examples of (conductors or insulators) | insulators |
| the air in a greenhouse is heated by (conduction or radiation) | radiation |
| thermal energy always moves from a warmer area to a (cooler or hotter) area | cooler |
