Four molecules have speeds 1m/sec, 4m/sec, 8m/sec and 16m/sec. The root mean square speed of these molecules (in km/sec) is :

Four molecules of gas have speeds 1,2,3 and 4 km//s .The value of the root mean square speed of the gas molecules is

Four molecules of a gas have speeds 2, 4, 6 and 8 kms^(-1) respectively. Calculate their root mean square speed.

The root mean square speed of hydrogen molecule at 300 K is 1930m/s. Then the root mean square speed of oxygen molecules at 900K will be………..

Change a speed of 12 m/sec into km/hr.

Change a speed of 12 m/sec into km/hr.

What will be the root mean square velocity of oxygen gas in m//"sec" at 300K?

Gas molecules each of mass 10^(-26) kg are taken in a container of volume 1 dm^(3) . The root mean square speed of gas molecules is 1 km sec^(-1) .What is the temperature fo gas molecules. (Given : N_(A) =6xx10^(23),R=8J//mol.K )

Convert each of the following speeds into m/sec : 90km/hr

Convert each of the following speeds into m/sec : 27 km/hr

The most probable velocity of the molecules of a gas is 1 km/sec. The R.M.S velocity of the molecules is
