Q7: Three identical flasks contain three different gases at standard temperature and pressure. Flask A contains CH4, flask B contains O3, and flask C contains N2. Which flask contains the largest number of molecules?

Flask A

Explanation:

Cause it has high gas temperature

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.

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.
