gcse AQA physics P1 (100% all correct answers)

how is heat transferred from place to place? correct answers conduction, convection, radiation What surface is better at absorbing heat? correct answers dark matt surfaces what surface is better at reflecting heat? correct answers light shiny surfaces what objects emit infared radiation? correct answers all objects. the hotter it is, the more it emits. what does infared radiation involve? correct answers waves! not particles what can radition pass through? correct answers vaccum particles in solids, liquids and gases have ? amounts of energy correct answers different describe the particles in a solid correct answers close together particles, with a regular pattern.They vibrate and stay in a fixed position describe the particles in a liquid correct answers close particles with a random patter. Move around eachother describe the particles in a gas correct answers far apart, random pattern, move quickly and in any direction what is conduction correct answers when heat energy moves through a substance are metals, or non metals better conductors correct answers metals what are non metals and gases correct answers good insulators the hotter the metal is... correct answers the more kinetic energy the vibrations have what happens in convection correct answers particles with lots of heat energy get less dense and rise, replacing particles with less heat energy. what is it called when a liquid changes to a gas? correct answers evaporation what is it called when a gas changes to a liquid correct answers condensation what increases condensation rate? correct answers increase in temperature of gas what increases rate of evaporation? correct answers increase in temperature of liquid, increase surface area, air moving over liquids surface
