sound and heat 4.0 / 5 based on 1 rating ? Revision SkillsOtherNone Created by: mkenzieCreated on: 22-02-13 04:02 how is sound energy transferred? by vibrating particles 1 of 29 how would you make it easier for sound to travel if the particles were closer 2 of 29 why cant sound travel travel in a vacuum because it has no particles 3 of 29 where can sound be seen? in an oscillloscope 4 of 29 what is the frequency of the wave? how many waves pass a point in a second 5 of 29 what is a wavelength of a wave the distance travelled by one particle during 1 complete vibration 6 of 29 what kind of wave is sound longitudinal 7 of 29 what kind of notes do high pitches have? high 8 of 29 what kind of sound would you need to have with a large amplitude sounds with loud volumes 9 of 29 what is the speed of sound? 330m/s 10 of 29 create a poem/song memorising all of the different parts of the ear. must include: all of the features of the ear. 11 of 29 what is the decibel scale it measures the loudness of a sound 12 of 29 when do particles vibrate more? when they have a higher temperature 13 of 29 what state of matter does convection happen in? gases and liquids 14 of 29 what happens when liquids and gases heat up? they become less dense and rise 15 of 29 what causes convection currents? the rising and falling og hot an cool fluids 16 of 29 how is radiant heat energy given out? by all hot objects 17 of 29 does radiant heat energy need a material to travel through? no 18 of 29 what is conduction? where heat energy is passed on by vibrating particles 19 of 29 what state of matter does conduction happen in? why solids as the particles are touching and there are free electrons 20 of 29 how would you work out the speed of something? distance / time 21 of 29 how would you work out the distance of something? time x speed 22 of 29 how would you work out the time of something? distance / speed 23 of 29 question: a family set off from home and walk at average speed of 3.6km/h. how far will they travel in two hours? give your answer in km. distance (km) = speed (km/h) x time(h) = 3.6 x 2 = 7.2 km 24 of 29 question: how long would it take a woman to walk 10km if her average speed was 5.4km/h? time(mins) = distance(km)/speed(km/h) = 10 / 5.4 = 1.85hrs 25 of 29 frequency = ? pitch 26 of 29 amplitude = ? volume 27 of 29 decibels = ? volume 28 of 29 range = ? hertz 29 of 29
