Energy transfer by design 0.0 / 5 ? PhysicsEnergyGCSEAQA Created by: Mr_MackintoastCreated on: 22-02-17 17:48 What is the relationship between the temperature difference between an object and its surroundings and the rate at which energy is transferred? The greater the temperature difference, the greater the rate 1 of 5 What does the rate at which energy is transferred depend on (3)? The materials the object is in contact with, the shape of the object and the surface area of the object. 2 of 5 What can be used to maximise the rate of energy transfer to keep things cool? A good conductor, something painted dull black or something which has air flow around them maximised. 3 of 5 How do we minimise the rate of energy transfer to keep things warm? We minimise the transfer if energy by conduction, convection and radiation. 4 of 5 What can we use to minimise the rate of energy transfer? Something with is: a good insulator, white and shiny or prevents convection currents by trapping air in small pockets 5 of 5
