Question

(a) What is the average kinetic energy (in J) of helium atoms in a region of the solar corona where the temperature is 5.20 105 K?

(b) Suppose that the average velocity (vrms) of carbon dioxide molecules (molecular mass is equal to 44.0 g/mol) in a flame is found to be 8.48 102 m/s. What temperature in kelvin does this represent? K

(c) What is atmospheric pressure on top of Mt. Everest on a day when water boils there at a temperature of 80.0°C?
N/m2

(d) What is the relative humidity on a 25.0°C day when the air contains 13.0 g/m3 of water vapor? %

Explanation / Answer

you have asked multiple questions. as per chegg guidelines i can answer only one.Please raise different question for others

Average kinetic energy of the helium atom

            K = (3/2)kT

= (3/2)(1.38x10-23 J/K)[(520000+273)K]

=1.076*10^-17 J
