Heat and Thermodynamics question

2021 · 20 Jul · Shift 1 · Q49

JEE MainPhysicsHeat and ThermodynamicsMCQ+4 / −1
Consider a mixture of gas molecule of types A, B and C having masses mA < mB < mC. The ratio of their root mean square speeds at normal temperature and pressure is :
  1. A
    vA=vBevC{v_A} = {v_B} e {v_C}vA​=vB​evC​
  2. B
    1vA>1vB>1vC{1 \over {{v_A}}} \gt {1 \over {{v_B}}} \gt {1 \over {{v_C}}}vA​1​>vB​1​>vC​1​
  3. C
    1vA<1vB<1vC{1 \over {{v_A}}} \lt {1 \over {{v_B}}} \lt {1 \over {{v_C}}}vA​1​<vB​1​<vC​1​
  4. D
    vA=vB=vC=0{v_A} = {v_B} = {v_C} = 0vA​=vB​=vC​=0
