WebOct 8, 2016 · Explanation: Theoretically calculated Speed of sound in dry air at 0∘C or at 273.15 K is 331.3ms−1. At T ∘C the speed of sound can be found with the help of the expression cair(T) = 331.3√1 + T 273.15 ms−1. Inserting given values we get cair(20) = 331.3√1 + 20 273.15 cair(20) = 343.2ms−1, rounded to one decimal place Answer link WebLooking for the best portable air conditioner for your home or office in the UK?
