Solution
The correct option is B decreases Temperature and pressure are related and varies with respect to one another.At higher temperature the air molecules vibrate more vigorously. Consequently the air expands. If we consider a column of air mass above a unit area, then at higher temperature there would be lesser molecules in the column. As we know that the weight of these air molecules is the pressure, we can conclude that atmospheric pressure decreases with increase in temperature.
