Concept explainers
(a)
Interpretation:
The conversion of 25 μL to mL should be done.
Concept Introduction:
The SI unit for volume is Liters. Microliters (μL) is the smallest unit. The conversion of units is to facilitate the display of values of quantities.
(b)
Interpretation:
The conversion of 35 kg to g should be done.
Concept Introduction:
Objects that are weighed are often measured in terms of grams or kilograms. The conversion of units from kilograms or grams is done keeping their values same.
(c)
Interpretation:
The conversion of 2.36 mL to L should be done.
Concept Introduction:
The unit of measuring capacity or volume is in Liters or milliliters. The values are converted from liters to milliliters by using conversion factors and also for converting milliliters to liters.
(d)
Interpretation:
The conversion of 300 mL to qt should be done.
Concept Introduction:
The unit of measuring volume in liters or milliliters. This is the standard unit of measurement. The quart is an English unit of volume which is equal to a quarter gallon.
(e)
Interpretation:
The conversion of 3 cups to L should be done.
Concept Introduction:
The unit of measuring volume in liters or milliliters is the standard unit of measurement. Cups are also a unit of measurement of volume and are followed in U.S.
(f)
Interpretation:
The conversion of 2.5 tons to kg should be done.
Concept Introduction:
The unit of measurement for objects that are weighed is in terms of kilograms or grams. This is the standard unit of measurement. If the value is high, it is converted to tons and this is often used in the U.S. But each unit is converted accordingly using conversion factors.
