1infrared radiation is emitted by...
- Avery hot objects only
- Bsolids only
- Celectronic appliances only
- Dall objects
2[blank_start]Matt[blank_end] surfaces are better emitters than [blank_start]shiny[blank_end] surfaces and [blank_start]dark[blank_end] surfaces are better emitters than [blank_start]light[blank_end] surfaces.
- AMatt
- BShiny
- Cshiny
- Dmatt
- Edark
- Flight
- Glight
- Hdark
3Convection can only happen in a...
- Aliquid
- Bgas
- Csolid
- Dfluid
4Condensation on a surface can be increased by increasing the [blank_start]area[blank_end] of the surface or decreasing the [blank_start]temperature[blank_end] of the surface.
- Aarea
- Btemperature
- Chardness
- Dtemperature
- Earea
- Fhardness
5What changes the rate at which a substance changes temperature when heated?
- Aspecific heat capacity of the substance
- Benergy supplied too it
- Cits mass
- Dits shape
- Eits size
- Fits capacitance
6What features make a vacuum flask good at keeping hot drinks hot and cold drinks cold and why?
- Aplastic cap (plastic is an insulator) to minimise conduction and prevent evaporation
- Bdouble walled container to prevent conduction
- Csilvered inside surface to reflect radiation
- Dmatt inside surface to absorb heat
- Econductive metal cap to help transfer heat
- Fcopper spring for support and to conduct heat
- Gvacuum chamber to prevent conduction and convection
- Hvacuum chamber to prevent radiation
7Water molecules escape from a pan at room temperature in a well ventilated room. This is because of [blank_start]evaporation[blank_end] and it will continue until all the water has [blank_start]evaporated[blank_end].
- Aevaporation
- Bcondensation
- Cboiling
- Dmelting
- Eosmosis
- Fcooling
- Gevaporated
- Hcooled
- Ifrozen
- Jboiled
- Kstopped moving
8When insulating a home, [blank_start]fibreglass loft insulation[blank_end] can reduce energy transfer by conduction; [blank_start]cavity wall insulation traps air in[blank_end] small pockets to reduce convection and aluminium foil between a radiator and a wall panel can reduce energy lost by [blank_start]radiation[blank_end]. Draught proofing can also reduce energy lost by [blank_start]convection[blank_end].
- Afibreglass loft insulation
- Bsolar heating panels
- Ccavity wall insulation traps air in
- Ddouble glazed windows trap air in
- Eradiation
- Fconduction
- Gconvection
