At what temperature will the velocity of CO2 molecules equal the velocity of oxygen molecules at 0°C?
Solution:
The given word problem is about Kinetic Molecular Theory because it involves the velocity and temperature of gases. The velocity of a gas at a certain temperature is
where:
u = velocity of a gas
R = universal gas law constant
T = absolute temperature of a gas
M = molecular weight of a gas
Hence, the temperature of CO2 in K if its velocity is equal with O2 is
Therefore, the temperature of CO2 in °C is
