Physics 1 P1 0.0 / 5 ? PhysicsMajority of the topics in Physics 1a and 1bGCSEAQA Created by: rachelwalkerCreated on: 26-09-15 14:56 How is heat transferred? Radiation, conduction or convection 1 of 17 Heat radiation is the transfer of heat energy by...? Infrared radiation 2 of 17 Conduction and convection involve the transfer of energy by...? Particles 3 of 17 When does convection occur? Convection occurs when the more energetic particles move from the hotter region to the cooler region and take their heat energy with them 4 of 17 What is condensation? Condensation is when gas turns to liquids 5 of 17 What is evaporation? Evaporation is when liquid turns to gas 6 of 17 What are 5 examples of insulation? loft insulation, hot water tank jacket, double glazing, draught-proofing and cavity wall insulation 7 of 17 What is the equation for payback time? Payback time= initial cost/ annual saving 8 of 17 What is the equation for specific heat capacity? Energy transferred= mass x specific heat capacity x temperature change (E= m x c x 0) 9 of 17 List the nine types of energy electrical, light, sound, kinetic, nuclear, thermal, gravitational potential, elastic potential and chemical energy 10 of 17 Equation for efficiency? Efficiency= useful energy out/ total energy in 11 of 17 What are the units for energy? Kilowatt- hours (kWh) 12 of 17 4 examples of non renewable resources coal, oil, natural gas and nuclear fuels 13 of 17 8 examples of renewable resources wind, waves, tides, hydroelectric, solar, geothermal, food and biofuels 14 of 17 How is electricity distributed? Via the national grid 15 of 17 Why is it much easier to boost the voltage up really high? Because having high current makes you lose loads of energy through the heat in the cables 16 of 17 List the EM waves Radio, micro, infrared, visible, ultra violet, X- Ray and gamma 17 of 17
