Question

for a gas the rms speed at 800 k is​

Answer 1

Answer:

twice the value at 200 K

Explanation:

Vrms = √(3RT/Mo)

Hence

Vrms ∝ √T

{Vrms2/Vrms1} = √(T2/T1)

T1 = 800K. Let T2 = 200K

then {Vrms2/Vrms1} = √{200/800} = (1/2)

i.e. Vrms1 = 2 × Vrms2

i.e. RMS velocity at 800K i.e. Vrms1 is twice of Rms Velocity at 200 K..

Answer 2

Answer:

twice the value at 200 K

Explanation:

Vrms = √(3RT/Mo)

Hence

Vrms ∝ √T

{Vrms2/Vrms1} = √(T2/T1)

T1 = 800K. Let T2 = 200K

then {Vrms2/Vrms1} = √{200/800} = (1/2)

i.e. Vrms1 = 2 × Vrms2

i.e. RMS velocity at 800K i.e. Vrms1 is twice of Rms Velocity at 200 K..
