Question

How much faster does sound travel on a hot summer day, 40 °C, than on the coldest winter day, -40 °C?

Answer 1

We will determine the velocities as follows:

hot day:

`V_(hot)=331+0.59(40)\Rightarrow V_(hot)=354.6m/s`

Cold day:

`V_(cold)=331+0.59(-40)\Rightarrow V_(cold)=307.4m/s`

So, in the hottest day the speed of sound will be moving 47.2 m/s faster than in the coldest day.
