Which statements describe the results of the effect of angle of insolation on absorption experiment? Check all that apply.

At 3 minutes, the soil temperature at a 0° angle of insolation is higher than at 90°. At 6 minutes, the soil temperature at a 45° angle of insolation is higher than at 0°. At 9 minutes, the soil temperature at a 90° angle of insolation is lower than at 45°. At 12 minutes, the soil temperature at a 45° angle of insolation is lower than at 0°. At 15 minutes, the soil temperature at a 90° angle of insolation is higher than at 45°.

Which of the following is a false statement about dispersion forces? View Available Hint (s) Which of the following is a false statement about dispersion forces? Dispersion forces are the result of fluctuations in the electron distribution within molecules or atoms. Dispersion forces are present in all atoms and molecules. Dispersion forces result from the formation of instantaneous dipoles in a molecule or atom. Dispersion forces always have a greater magnitude in molecules with a greater molar mass. Dispersion force magnitude depends on the amount of surface area available for interactions.
