For a given ideal gas the sound speed depends only on its temperature. At a constant temperature, the ideal gas pressure and density have no effect on the speed of sound, because pressure and density (also proportional to pressure) have equal but opposite effects on the speed of sound, and the two contributions cancel out exactly. hence Option D. is the correct option T = temperature in degrees Celsius.

The Speed of Sound . The first analytical determination of the speed of sound was given by Isaac Newton in Proposition 49 of Book II of the Principia. For sea level air at a typical ambient temperature he computed a value of 979 ft/sec, which is too low by about 15%, the true value being about 1116 ft/sec Check Out Speed And Temperature On eBay. Find It On eBay. But Did You Check eBay? Find Speed And Temperature On eBay Calculate the speed of sound by dividing the speed that the sound traveled (from Step 6) by how long it took to travel that distance (from Step 7). Record the outdoor temperature that day. Repeat this experiment on days that have very different temperatures. You may also want to try it at different times of the day, since it is cooler in the. Now let's calculate a prediction for what we think the speed of sound should be. The speed depends on the temperature: v = 331m/s + 0.6 T, where T in this equation is the temperature in °C. Assume that room temperature is T = 20°C. Calculate the predicted value for the speed of sound, v . v = 319m/s

Symbol c or cs. The speed at which sound waves are propagated through a material medium. In air at 20°C sound travels at 344 m s−1, in water at 20°C it travels at 1461 m s−1, and in steel at 20°C at 5000 m s−1. The speed of sound in a medium depends on the medium's modulus of elasticity (E) and its density (ρ) according to the relationship c = √(E/ρ) The speed of sound is the distance travelled per unit time by a sound wave as it propagates through an elastic medium. In dry air at 20 °C (68 °F), the speed of sound is 343.2 metres per second (1,126 ft/s; 1,236 km/h; 768 mph; 667 kn), or a kilometre in 2.914 s or a mile in 4.689 s.In common everyday speech, speed of sound refers to the speed of sound waves in air The great question is that since sound is a mechanical wave, its speed is influenced by the medium of propagation and also by the temperature. In most cases, the techniques reported for that goal usually make use of expensive equipment and techniques that may not be affordable and/or easy to implement in schools, which is an experimental limitation for the teachers to show this influence on. Converting these units to an absolute temperature scale produces values of 434°R in the English system and 241 K in Metric units. Let us now solve the speed of sound equation using these values. This methodology tells us that the standard sea level speed of sound on Mars is equal to. 801.3 ft/s. 244.2 m/s At 25 C, the speed of sound is 1,246 kilometres per hour.
