How does conduction occur?
Conduction of heat energy is the process where vibrating particles pass on their extra kinectic energy to neighboring particles.
1 of 10
What factors must be perfect for a particle to escape from wter and evaporate?
a) Enough Energy b) Travelling in right direction c) Near enough to surface
2 of 10
What does rate of reaction depend on?
Temperature, surface area, airflow
3 of 10
When does convection occur?
Convection occurs when the more enrgectic particles move from the hotter region to the cooler region and take their heat with them.
4 of 10
How can a house be made for cost effective?
Loft insulation, water tank cover, double glazing, draught proofing, cavity wall.
5 of 10
What happens with every electrical device?
Energy input -> Useful energy & Wasted enrgy -> Useful output
6 of 10
What can energy never be?
Destroyed
7 of 10
What type of heat does a TV give out?
Light, sound and heat
8 of 10
What is a step up transformer and why is it usefuL?
Voltage is transformed to high because current is low. If transported at lower volateg, current high, energy wasted through heat.
