(Tarih:14.01.2014)




Because the average kinetic energies of molecules ofdifferent gases are equal at a given temperature, and thekinetic energy of a molecule is directly proportional to its mass and the square of its velocity, molecules of gases that have lower molecular weights have higher average velocities than molecules of gases that have higher molecular weights. At 25°C, does every molecule of hydrogen (H2) have a higher velocity than every molecule of oxygen (O2)? Would any molecules of hydrogen have velocities near 0 m/s? Would any molecules of oxygen have velocities greater than the average velocity of all the hydrogen molecules?

soru ingilizce kısaca soru kökleri :
1-)25 derecede H2 O2 den ne kadar hızlıdır?
2-)H2 molekülünün hızı 0 m/s yakınmıdır?
3-)O2 herhangi bir anda H2 molekülünden hızlımıdır?
