26. a megagram = 10⁶ grams while a kilogram = 10³ grams, so the megagram is bigger

28. a mililiter = 10⁻³ liters while a microliter = 10⁻⁶ liters, so the mililiter is bigger

36.   1 meter is equal to 100 centimeters, so the decimal moves right 2 places

37. 1 micrometer is equal to 0.001 milimeters, so the decimal moves left 3 places

38. 1 centimeter is equal to 0.00001 kilometers, so the decimal moves left 5 places

39. 1 micrometer is equal to 10⁻¹² megameters, so the decimal moves left 12 places

40. 1 kilometer is equal to 100000 centimeters, so the decimal moves right 5 places

relative humidity is a measure of how much water an air mass at a given temperature can hold.

<u>Explanation:</u>

When a quantity of air at a supplied temperature exists the highest volume of water vapor, the air is considered to be saturated. The relative humidity is the water-vapor content of the air corresponding to its content at fullness.

Relative humidity can be described as the quantity of water vapor in air at a provided temperature related to what that air could endure at that temperature. We can thus adjust the relative humidity of an air bundle by either raising or lowering the volume of water vapor in the parcel OR by boosting or reducing the temperature of the air mass.
