Energy Flashcards
1
Q
Describe conduction
A
Vibrating particles transfer energy to neighbouring particles
2
Q
How to reduce convection
A
Stop free flow of fluids
= sleep under blanket
3
Q
Similarities of convection and conduction
A
Both involve particles gaining kinetic energy
4
Q
Difference of convection and conduction
A
Conduction
= only energy is transferred
Convection
= particles move
5
Q
Describe the conservation of energy principle
A
Energy can be transferred usefully, sorted or dissipated but never created or destroyed
6
Q
Problem with friction
A
Reduces efficiency of energy transfer
= use lubricant like oil
7
Q
Energy conservation methods
A
- double glazing
- cavity wall insulation
- loft insulation
- carpets
