Question

match each item with the correct base unit of the metric system used to measure the item.
1 meter
2 temperature
3 gram
4 liter
match each of the options above to the items below.
powdered chemical
height of a tree
amount of water in a test tube
heat of a water bath

Explanation:

Step1: Analyze "powdered chemical"

A powdered chemical's quantity is measured by mass, and the metric base unit for mass is Gram. So powdered chemical matches with 3. Gram.

Step2: Analyze "height of a tree"

Height is a measure of length, and the metric base unit for length is Meter. So height of a tree matches with 1. Meter.

Step3: Analyze "amount of water in a test tube"

The amount of a liquid (water) is measured by volume, and the metric base unit for volume is Liter. So amount of water in a test tube matches with 4. Liter.

Step4: Analyze "heat of a water bath"

Heat (temperature) of a water bath is measured by temperature, and the metric base unit for temperature is Kelvin (but in the given options, "Temperature" is the category). So heat of a water bath matches with 2. Temperature.

Answer:

powdered chemical - 3. Gram
height of a tree - 1. Meter
amount of water in a test tube - 4. Liter
heat of a water bath - 2. Temperature
