Sodium, potassium, strontium, calcium, and magnesium
Because of the temperature chance and the pollution
The relation between the mass, average speed, and temperature is given by:
u = √(3RT/M)
It is given that, temperature is 35 degree C = 35 + 273 = 308 Kelvin
The molar mass of oxygen = 0.032 kg/mole
r = 8.314 j/(mol-k)
u = √(3 × 8.314 × 308 / 0.032)
u = 489.966 m/s
