Created by StemPy LabA fixed amount of an ideal gas is heated at constant pressure from to . It is then squeezed at constant temperature to half its volume. Compared with the start, how have the mean free path of a molecule and the number of collisions it makes each second changed?

← A vessel holds 6.0 g of helium and 32.0 g of oxygen, both ideal gases, at the same temperature. Oxygen molecules are rigid and diatomic, and the molar masses are 4 g/mol and 32 g/mol. What is the ratio of the internal energy of the oxygen to that of the helium?In an ideal gas at temperature T, the number of molecules with speeds between v and v + dv is proportional to v² e^(-mv²/(2kBT)) dv. Take a small, fixed speed range dv. How does the number of molecules with speeds in a range dv at the rms speed compare with the number in a range dv at the most probable speed? →
