reducing energy loss Flashcards
1
Q
what is conduction?
A
how heat travels in solids
2
Q
what is convection?
A
how heat travels in liquids/gases
3
Q
what is infra red radiation?
A
how heat travels through a vacuum and from surfaces
4
Q
how can you reduce conduction?
A
by making things thicker
by using insulating material
5
Q
how can you reduce convection?
A
by trapping air so it can’t circulate
6
Q
how can you reduce infra red radiation?
A
by making the surface shiny
(shiny/light surfaces are low emitter and will reflect the infra red back)
7
Q
name some factors that affect the rate of heat loss
A
temperature difference
thickness of material
area surface
surface nature (light/dark)
