Homework Answers
1. False ( true statement - Kinetic energy will be same for H2 and CO2 .)
Reason - K.E. = 3/2 k*T. K = boltzman constant .
K.E. is only depend upon temperature .
2. False ( RMS speed of H2 will be higher than CO2 .)
Reaosn - RMS speed is inversely proportional to molar mass.
3. True
4. True
5. False ( denisty will be different. )
