- A hypothetical speed distribution of gas molecules is defined as follows: P(v) = 0 for 0≤v < vo P(v) = 0.21 for vo ≤ v << 2vo P(v) = 0 for 2v0 < v where P(v) is the probability distribution as a function of speed, v. a) Use the normalisation condition to find the value of v. b) What percentage of the gas molecules has its speed between vo and/vo? c) What percentage of the gas molecules has its speed between 0 and 2 ?In the question its asks for the rate of energy transfer P after you find what the interface temperature T is. Upon completion from submitting T in into the intial rate equation the final expansion gives: P = A(Th - Tc) / (L1/ k1) + (L2/ k2) I understand how T was achieved from expanding the P1 = P2 substitution, but how is P found from inserting T into P1 = k1A (T - Tc / L1)?How does the density of He-gas at 22C compare to the density of air at 22C?
