Oxygen at 1 atm. pressure and 0C has a density of 1.4290 gm/L. root mean square speed would be:

Explanation:

P=1 atm=101.3×103Pa

d=1.4290 g L−1=1.4290 kg m−3

We know that,

c=d3P=1.42903×101.3×103=461.15 ms−1

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.
