In general, meteorologists do not consider day-to-day forecasts for more than a week or 10 days ahead to be possible, and the best forecasts are for five days or less into the future.n general, meteorologists do not consider day-to-day forecasts for more than a week or 10 days ahead to be possible, and the best forecasts are for five days or less into the future.
This phenomenon is referred to as freezing point depression. The mathematical equation describing freezing point depression is: Î´T = (Kf)(m). Î´T represents the freezing point depression: Î´T = Tfo-Tf. Tfo is the freezing point of the pure solvent. Tf is the freezing point of the solution. Kf is the molal freezing point depression constant, which has a characteristic value for a given solvent. The units of Kf are given in oC/m. is the molality of the solution.
Best Answer: Molality is used in determining the change in freezing point and boiling point. The particles of solute interfere with the process of freezing and ...
