At STP

THe raat mean square velocity of an ideal gas in a container of fixed volume is increased from 5 x 10^4 cm/s to 10 x 10^4 cm/s . which of the following statement correctly explains how the change is accompolished 50 mol H2 gas and 1.0 mol He gas (a) Have equal average kinetic energies [...]

Equal moles of hydrogen and oxygen gases are placed in a container with a pin-hole through which both can escape. What fraction of the oxygen escapes in the time required for one-half of the hydrogen to escape? 50 mol H2 gas and 1.0 mol He gas (a) Have equal average kinetic energies (b) Have equal [...]

According to kinetic theory of gases, for a diatomic molecule (a) The pressure exerted by the gas is proportional to teh mean velocity of the molecules (b) The pressure exerted by the gas is proportional to the root mean square velocity of the molecules 50 mol H2 gas and 1.0 mol He gas (a) Have [...]
