Which of the following volumes is the smallest? a) one microliter b) one deciliter d) one liter c) one milliliter

The correct answer option is a) one microliter.

Explanation:

We are given four different units of measuring the volume of a liquid and we are to determine whether which of them is the smallest of all.

Comparing the given values with 1 liter quantity:

a) 1 microliter - it equals to 0.000001 liters

b) one deciliter - it equals to 0.1 liter

c) one liter - 1 liter

d) one milliliter - it equals to 0.001 liter

So the smallest value is one microliter.

a) one microliter

Explanation:

The advantage of the SI (International system of measurements) is that everything is in base 10, and the prefix indicates the power of 10.

For the volume, the base unit is the liter.

one microliter = 0.000001 liter (one millionth, 1 / 1000000, of a liter)

one deciliter = 0.1 liter (one tenth, 1/10, of a liter)

one liter = 1 liter

one milliliter = 0.001 liter (one thousand, 1/1000, of a liter)

As you can see, a microliter is by far the smallest of these units.
