Homework Sourseif an ideal gas molecule has a speed of 050kms at 20 celcius
if an ideal gas molecule has a speed of 0.50km/s at 20 celcius, what is the speed at 80 celcius?

if an ideal gas molecule has a speed of 0.50km/s at 20 celcius, what is the speed at 80 celcius?
Solution
the speed is directly proportional to square root of the temperature.
so,
v2/v1 = sqrt[T2/T1]
v2 = sqrt[T2/T1] * v1
= sqrt[80+273 / 20+273]*0.50 km/s
= 0.5488 km/s
