Question 1 Answer Gases can be converted to liquids by compressing the gas at a suitable temperature. Gases become more difficult to liquefy as the temperature increases because the kinetic energies of the particles that make up the gas also increase. The critical temperature of a substance is the temperature at and above which vapour of the substance cannot be liquefied, no matter how much pressure is applied. www.cafesciredruth.co.uk Email: info@cafesciredruth.co.uk

Question 2 Answer On the decibel scale, the smallest audible sound (near total silence) is 0 dB. A sound 10 times more powerful is 10 dB. A sound 100 times more powerful than near total silence is 20 dB. A sound 1,000 times more powerful than near total silence is 30 dB. www.cafesciredruth.co.uk Email: info@cafesciredruth.co.uk

Question 2 Answer On the decibel scale, the smallest audible sound (near total silence) is 0 dB. A sound 10 times more powerful is 10 dB. A sound 100 times more powerful than near total silence is 20 dB. A sound 1,000 times more powerful than near total silence is 30 dB. www.cafesciredruth.co.uk Email: info@cafesciredruth.co.uk

Question 2 Answer Any sound above 85 dB can cause hearing loss, and the loss is related both to the power of the sound as well as the length of exposure. You know that you are listening to an 85-dB sound if you have to raise your voice to be heard by somebody else. Eight hours of 90-dB sound can cause damage to your ears; any exposure to 140-dB sound causes immediate damage (and causes actual pain). www.cafesciredruth.co.uk Email: info@cafesciredruth.co.uk

Question 2 Answer Near total silence - 0 dB A whisper - 15 dB Normal conversation - 60 dB A lawnmower - 90 dB A car horn - 110 dB A rock concert or a jet engine - 120 dB A gunshot or firecracker - 140 dB Distance affects the intensity of sound -- if you are far away, the power is greatly diminished. All of the ratings above are taken while standing near the sound. www.cafesciredruth.co.uk Email: info@cafesciredruth.co.uk
