For one mole of an ideal gas, preacing the temperature from 10 C to 20 C
A) increases the average kinetko energy by two meg
increases the res velocity by 2 times
increases the rms velocity by two tamo
increases both the average letsey and welcity, but not significantly
A​

Answer 1

Answer:

given = temprature = 10° to 20°

273 + 10 = 283K

273+20= 293K

solution, =

final temprature =293K

KE₁/KE₂ =T₁/T₂ = 283/293= 0.96

K.E2 = 1.04KE1

We know that,

Vrms = $\sqrt{3RT/M}$

v1/v2 = $\sqrt{T1/T2} = \sqrt{283/293}$

V2 = v1 $\sqrt{293/283} = 1.02v1$

both avarage and rms velocity increases but not significantly.

so, option D is correct answer.
