Physics P1! 2.0 / 5 based on 1 rating ? SciencePhysicsGCSEAQA Created by: Shannon RibtonCreated on: 27-12-12 16:10 What does specific Latent Heat mean? The energy that is needed to change the state of a material. (the energy break bonds) 1 of 6 Why are metals good conductors? They have free electrons. 2 of 6 Why is air such a good insulator? It is a gas so there are less collisions due to less particles in an area. This means the energy cannot be passed on as easily. 3 of 6 The hotter an object is the more/less radiation it emits? More. 4 of 6 What type of surface reflects Radiation waves the best? Shiny. 5 of 6 Efficiency is the measurement of what? And how how to we calculate it? How much useful energy anl appliance produces. It is calculated by dividing (useful energy output)by (total eneergy input) 6 of 6
