For one mole of an ideal gas, increasing the temperature from 10^(@)C to 20^(@)C.

Answer»

increases the average kinetic energy by two times
increases the RMS by `sqrt(2)` times
increased the rms by 2 times
increases both the average kinetic energy and rms VELOCITY but not significantly

Solution :`bar(KE)=(3)/(2)RT :. (bar(KE_(2)))/(bar(KE_(1)))=(T_(2))/(T_(1))=(293)/(283)=1.04`
`:. bar(KE_(2))=1.04bar(KE_(1))`
`u_(rms)=sqrt((3RT)/(M))`
`:.(u_(2))/(u_(1))=sqrt((293)/(283))=sqrt(1.04)=1.02`
`:. u_(2)=1.02" u"_(1)`
Thus, both INCREASE but not significantly.
