Here h2 is the lightest element and it also directly proportional to the temperature that's why A is the right answer.

Gas molecules moves very high in the negatives because is more dry and therefore molecules can really move freely.

C is the correct option. As with increase in temp kinetic energy increase which increase the speed of molecules.

As molecules has greatest speed in high temperature but in option A there is -72 isn't it is lower temperature?

Everyone knows H2 is very light but the mass of others like N2 should be known for calculation: temp/mass.

Hydrogen will have the highest speed by the formula of root mean square velocity = square root of 3RT/ M.

As according to 'higher the temp. Higher will be speed' then out of all 4 N2 must have higher speed.

Options 1 is right answer. Because in relation, 3RT/M so H2 have the lowest mass among all options.

Kinetic Energy is directly proportional to its temperature according to kinetic theory of gas.

I think A is right. Because hydrogen is a lightest gas and mass decrease then speed increase.
