Q. 2.4 - An Introduction to General, Organic, and Biological Chemistry

Question

State the type of measurement in each of the following statements:
a. I rode my bicycle $15 km$ today.
b. My dog weighs $12 kg$ .
c. It is hot today. It is $30°$ .
d. I added $2L$ of water to my fish tank.

Step-by-Step Solution

Answer

a. The type of measurement is length.

b. The type of measurement is mass.

c. The type of measurement is temperature.  

d. The type of measurement is  volume 

Part (a) step 1: Given Information

We need to find the type of measurement.

Part (a) step 2: Explanation

Now, make understand that $15 km.$Km is an abbreviation for a Kilometer, which is the unit of length Kilometer(km) is equal to one thousand meters (m), which is the SI unit of length.

Therefore, the type of measurement for this statement is length.

Part (b) step 1: Given Information

We need to find the type of measurement.

Part (b) step 2: Explanation

Now, make understand that $12 kg$ is an abbreviation for a Kilogram, which is the unit of length Kilogram(kg) is equal to one thousand grams (g), which is the SI unit of length.

Therefore, the type of measurement for this statement is mass.

Part (c) step 1: Given Information

We need to find the type of measurement.

Part (c) step 2: Explanation

Now, 

explain what $30°C$means $°C$ is an abbreviation for  a degree Celsius, which is the metric unit of temperature.

Therefore, the type of measurement for this statement is temperature.

Part (d) step 1: Given Information

We need to find the type of measurement.

Part (d) step 2: Explanation

We need to explain what $2L$means. $L$ is an abbreviation for a liter, which is the metric unit of volume liter (L) is equal to one cubic decimeter ($d{m}^3$) and to a thousandth of a cubic meter $\left(m^3\right)$.

Therefore, the type of measurement for this statement is volume.
