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. 9 of 10 What ahppens to the light ehn it hits a mirror? It reflects perfectly and a mirror image is created 10 of 10
