Part A: In a gas that is a mixture of water (two H and one O) and carbon dioxide

Question

Part A:

In a gas that is a mixture of water (two H and one O) and carbon dioxide (one C and two O), if the water has average velocity of 707 m/s, what is the average velocity of the carbon dioxide molecule?

Part B:

An oxygen molecule in a flame at 2000 K would have an average energy in joules

a. [1.66 x 10 ^ -10]

b. [1.38x10 ^-20]

c. [2.76 x 10 ^-20]

d. [4.14 x 10 ^-20]

Part C:

Which of these are not fundamental particles, but are composites of quarks held together by gluons?

Select all that apply.

a. Protons

b. Neutrons

c. Mesons

d. Electrons

Explanation / Answer

A) VH2o/ VCO2= sqroot ( MCo2/ MH2o)

707/ VCO2 =sqroot ( 44/18)

Vco2= 453.205 m/s apprx

b)K =1/2 KT = 1/2 ( 1.38 x 10^-23) (2000) = 1.38 x 10^-20 J

c) protons and mesons
