Two flasks A and B of equal volume containing equal masses of H 2 and C H 4 gases are at 100 K and 200 K temperature, respectively. Which of the following is true about the total KE (kinetic energy)?

Question

Two flasks A and B of equal volume containing equal masses of H 2 and C H 4 gases are at 100 K and 200 K temperature, respectively. Which of the following is true about the total KE (kinetic energy)?, Total KE of H 2 is four times that of C H 4, Total KE of C H 4 is four times that of H 2, Total KE of H 2 is two times that of C H 4, Total KE of C H 4 is two times that of H 2

MARKS App · Accepted Answer

Total KE = K E - (per mole) × Moles of molecules Total K E A = 3 2 R T A n A n A = m 2 n B = m 16 So n A n B = 8 So T o t a l K E A T o t a l K E B = T A N A T B N B = 1 2 × 8 = 4 .
