The average KE per molecule (also per atom in this case) is constant. Look up the atomic masses of neon and argon, m(Ne) and m(Ar). v = sqrt(2KE/m) ==> v(Ar) = v(Ne)*sqrt(m(Ne)/m(Ar)).

... to is called the coefficient of thermal expansion (the amount of energy needed to heat up 1 cm^3 of material one degree). The units for the coefficient is (10^(-6))/degrees. You'll often see this...

The energy from the banana must be converted to Joules So 100kcal= 100000cal*4.184J/cal = K = 1/2*m*v^2 so v = sqrt(2*K/m) This is where your eqn is in error So v = sqrt(2*418400/82) = 101m/s

Multimode heat transfer is an incredibly difficult problem. You need to learn to think of thermal resistances in parallel and series. For instance, for heat loss of the windshield surface, convection is in parallel with radiation, and this parallel...
