Explain why in light of kinetic molecular theory. Select all that apply. Gases behave ideally when both of the following are true: (1) The pressure exerted by the gas particles is small compared to the space between them. (1) The volume of the gas particles is small compared to the space between them. (1) The volume of the gas particles is large compared to the space between them. (2) The forces between the gas particles are significant. At high pressures, the number of molecules per unit volume decreases, so the volume of the gas particles is much greater; and because the spacing between the particles is much smaller, the interactions become more significant (2) The forces between the gas particles are not significant. At high pressures, the number of molecules per unit volume increases, so the volume of the gas particles is much greater; and because the spacing between the particles is much smaller, the interactions become more significant.
